If that's what your budget is, the PSR225 is probably the best sounding keyboard for the money. It also has those real piano samples (stereo I think) that sound pretty good. It would be a whole lot better if Yamaha added a pitchbender to it.
The 61 key keyboard is a little short for real piano work but can suffice for a beginner. The keyboard does have a pretty nice feel though.
The 32 polyphony and 16 multitimbral are both good for the money and beginning midi creating. It will work well with a sequencer and computer. And the instrument sounds aren't really that bad for a low end board.
As Albert says, it does borderline on being a toy but for $200 it's a good board. You can always upgrade later.
