Okay.... scratch off the Yamaha's, the Roland XV-88, and the Alesis's from your list....... Ok, now add the Yamaha PSR 540,640,740 and 8000, and 9000...... also add the Ensoniq ZR-76, Roland G-1000 (maybe, I don't know much about this one) and maybe the Korg Trinity (A weaker version of the Triton, I think) and N264/364 (Korg's synths before the Triton/Trinity) Here's why.... the ones I had you get rid of have no way to record songs without an external sequencer and no drum accompaniment built in..... the ones I had you add have sequencers on board (I think they all do anyhow) and drum accompaniment on most of them. Ok now you should be looking at something like this: Roland XP 60 and 80, and Roland G-1000; Yamaha PSR series (above 340 at least); Korg N series and Triton/Trinity; and the Ensoniq ZR-76. Okay.
Now heres what all this stuff does.... you said you wanted drum accompaniment, the ones I listed that would do that (without programming) are the PSR's, the ZR-76 and the G-1000. The ZR-76 has a drum machine onboard..... this would give you some good drum tracks, the other ones have "styles" these include drum parts, piano parts, rhythm guitar, etc. I believe you can normally mute some parts to get just the drums. (not sure) The other ones (XP's and Korg's) you would have to program in some drum tracks via the internal sequencer or put some drum traks on disks as midi files and play those. I don't think these have onboard drum accompaniment.
As for "recording stuff" all the ones I listed have sequencers of some sort.... this would let you either play what you wanted to record in real time, program it in step time (step by step), or use a software midi sequencer on a PC to program the recording.. save it to a disk and most of those keyboards will play that. I've heard that the Ensoniq ZR-76 has a good sequencer... the Triton is good.... the Roland XP's are good.... this isn't to say that the other's aren't any good, just not AS good. The Roland G-1000 is probably good too.
As for sounds.... for acoustic pianos, the ZR-76 is supposed to be very good, the XP's are good and the others are probably just a step below that. (a small step), for electric pianos, I would guess the ZR-76 is also good here, all the others will probably be very good too. Really all the ones I listed should have good sounds, the only ones that might be a bit lower quality would be the lower PSR's and maybe the Korg N series.
Having onboard speakers would make transporting stuff to and from the church a lot easier, but most of these keyboards do not have onboard speakers. Also onboard speakers would probably be a little harder to get the sound loud enough to hear well in a church. You would probably want to hook up the keyboard to an external amp anyway. There are some fairly good amps out there that don't cost much..... Roland KC-100 and 300 are fairly good, and are like $200-350. I'm sure there are others too. The only keyboards I have listed that have onboard's are the Yamaha PSR's.
The reason why the Triton is so much more expensive is really quite understandable..... first of all it has a sampler, this allows you to record any sound you want (Choir singing, violin, saxophone, etc.) and play it with the keyboard... cool huh?? Also it has like 6 outputs and five pedal inputs (compared to about 4 outs and 4 pedals for most others) I believe it also has an effects processor for an external mic or guitar.... plug in a mic and add echo, etc. None of the other keyboards I listed have these things... I don't think so anyhow.
Things to consider when buying a keyboard...... polyphony (number of notes that can sound at once) divide by how many tones are playing to get what you actually have. 64 should be sufficient. Weighted or un-weighted keys (like a piano or like a synth??) pedal inputs (how many does it have, how many do you need), how the thing sounds to you (do you like it), how the thing feels (do you like playing it) etc. etc.
My recommendation...... I guess Ensoniq ZR-76 or Roland G-1000.... These would be easier to use as you wouldn't have to program everything in first....
The prices on everything I listed is as follows: Ensoniq ZR-76 - $1800; Yamaha PSR 540,640,740,8000,9000 - $500, $900, $1300??, $2400???, and $2800; Roland XP 60,80 - $1400,$1600, G-1000 - $1200; Korg N264,364 - $1100 each, Trinity,Triton - $1700, $2200?? All these prices are off
www.zzounds.com this is also a good place to compare them.
Sorry I don't know anything about the new Korg.... you might find it at that site I put down..... any ideas yet???
