So 61 keys and built in speakers wasn't all THAT important after all?
Oh, and trust me, James, having caps lock on is the LEAST of the rudeness that goes on here..
They may be more than your budget allows, but I find the Mackie SRM150's to be quite excellent stage monitors. They may be more than you want to spend, but you can always start with just one (in all probability, most church PA's will be in mono, so hearing stereo for yourself is no big deal) and add the second later.
The thing that swings it for me is the sheer variety of connectors on the Mackie's - 1/4", XLR, RCA, pass-through jacks, phantom power, high impedance input for electric guitar, and a full 3-band EQ. It really is a Swiss Army Knife for monitoring purposes, plenty loud enough (150W), and has a handy mount on the underside for mounting on a mike stand.
I've got two, and they have been invaluable, not just for me, but if another player has any kind of monitoring issue, I can easily loan him or her one, and it's problem solved!
Without a small sub, I wouldn't even consider them for a small PA, in fact, I've never even been tempted to TRY them so far in this role. But for what you describe you need, they sound perfect. Perhaps the Podium 10"s might work, but they are much bigger and don't mount up as easily. Plus there are varying reports about their reliability. Mackie stand by what they make, and are easy to get serviced (not that I've needed that...)
They ARE multi-voltage (100-240V 50-60Hz), so that solves that issue...
Give them a try.
