Tim,
If all you will ever want to do is use the board at a worship service and you won't be needing any accompaniment, then the S90 is surely a good way to go. You'd be spending a lot more for pretty much the same sound palette with all of the added features of an arranger by going to the T2. If however, you ever think you'll want some backing, perhaps a PSR3000 would also do the trick, for a lot less, or... since your kb player wants 76 keys, you could even consider getting both an S90 and a PSR3k for roughly around the price of one T2. If you can wait a few more months, the 3k's successor will likely be announced.
I'm guessing there might be a reason why the 76 key PA1x isn't a possible consideration as well ?
