I helped choose a digital piano for our church about 3 years ago. We went for a Roland HP203 in the end. I think they're around £1500 now. As with anything else, you tend to get what you pay for, and I suspect the cheaper pianos wouldn't be as nice.
We didn't look at Yamaha, but considered the Clavinova. We liked the Roland because it has nicely wieghted keys, which feel more like an acoustic piano. Solari's right that you should go and try some out; obviously I don't agree with his conclusion, but you might! If what you want is easy transposition, choose the model that makes this easiest.
Digitals are ideal for an old building which only gets heated once a week in the winter. We have quite a large church, so needed to amplify the output, but you might get away with it in a smaller building. Good luck!
But beware - churches are known to harbour mice and if mice get into a digital piano they can wreck it! I speak from experience! My Clavinova was finished of by mice nibbling the wires and peeing on the circuits! The repairman (who arrived to declare it unrepairable) knows of churches that have had "mouse proof" boxes built to protect digital pianos!
What's more my insurance did not cover damage caused by vermin!
