Best Digital Piano

I'm looking for something that feels like and sounds like a piano. Transpose is important because I'm a church pianist, and we routinely transpose songs into more singable keys for the congregation. I haven't yet plunged into all the cool things that I could do with MIDI, all the different voices, etc., so that's much less important to me.

I'm currently using an m-audio 88sx (no longer made), and it's starting to fail (certain
combinations of keys cause some notes not to sound). I've had it about 3.5 years. It
definitely does not have a real piano feel, and while it has some touch sensitivity, it
doesn't have anywhere near what a real piano has. I am in the fortunate position of
being able to afford a better electronic piano, so I'm shopping. I came across your
guide, and it was very interesting, because I consider myself somewhat ignorant of what's generally available.

Since I wanted to actually play before I bought, I went to a nearby store (Gand Music
Sound in Northbrook, Illinois, USA), and tried a few different models they had on the
floor.

I eliminated the Yamaha model that was about $700 (sorry, didn't write down the model
number) because it didn't feel enough like a piano, and didn't have enough touch
sensitivity in my opinion. The two models at the top of my list right now are a Yamaha
P155 for $1,199 and a Yamaha CP50 for $1,699. I liked the feel of the keyboards and felt there was a fairly wide range of touch sensitivity. I'm leaning slightly towards the
CP50 because I think it will be more versatile if I do start doing more with voices and
recording. There was a Roland, I think it was the 700GX, but that was ~$2,100, and I was having a hard time seeing what more I would get that I would care about for the extra $400 over the CP50. I also tried a Kurzweil, I think it was the SP2XSP.

As a side comment, the Yamaha keyboards are good enough that I am seriously considering getting rid of my acoustic baby grand (it's old, and not of great quality), because I could genuinely enjoying playing them as my primary instrument. I'd probably need to get some more "living room friendly" (in terms of appearance) speakers (I currently have an Alesis Sumo 100 amp). The other bonus would be that I could play with headphones early/late/when someone else in the house wants to watch a movie.

I was on vacation for the last week, so I haven't had time to continue my shopping.
There are two other stores in my area that sell electronic stage pianos, and I want to go see what they had, and try a few more before I made my final decision.

I'm going to try downloading your guide again using a different e-mail address. I'll
probably be shopping for another 2-3 weeks by the time I get to the other two stores (Sam Ash Music in Buffalo Grove, IL and Music Center in Kenosha, Wisconsin).
