I wanted to mention that the M50 88 doesn't have aftertouch although it will respond to aftertouch when using MIDI IN/OUT from what I understand.
If 76 keys is acceptable to your church then that opens a wide range of other options for you as well Tim. Clavia makes the fully weighted 76 key Nord Stage but it is rather expensive at over $3,000. Also, Kurzweil has the PC3 76 key (fully weighted as well) which is more reasonably priced at about a $1,000 less than the Nord Stage 76. Both of those DO have an aftertouch feature by the way. As far as ease of use the Juno Stage is pretty straight forward but I haven't had the opportunity to play a Kurz PC3 yet. I have played the Nord Stage though and it seems pretty user friendly as well.
Half of the fun is just doing the shopping around eh?

All the best,
Mike
