If you want to do indoor high ISO without flash (so 1600+) then I share your concern.. If you are going to use a flash then don't worry about it... If you are not going to use a flash and just the kit lens (which isn't so bright) then good ISO 800 and 1600, will be an issue for you I imagine..

maxuum 5d - image stabalization a real plus - worry about support
I don't think 6mp is an issue at all...
d50 - only 6 mp compared to other two
you might want to try shooting RAW then
i usually set the camera to auto - try to fix pictures
valid points, I have large hands too, so I bought the battery grip for my Pentax ist D, makes a big difference, but that is just added cost and you said you didn't want that ;-)
canon xt and pentax ist feels to small - have larger hands
The choice is yours, you don't need our help ;-) They will all take great photos, I suggest you go try them all out and see which one feels best for you... Based on your description of your needs, I doubt any of them will be missing features you really need...
any help in choosing greatly appreciated
