get the 6mp that spanky posted & use the difference to buy a big memory card. unless you are doing pro quality work like nightshade, anything over 4-6mp is senseless.

i have a 6mp w/ a 512mb card & @ 2048x1536 pic size i can store about 600 pics. that size gives me the flexibility to crop & still be plenty big enought for very good resolution for 8x10 prints

here is what yahoo recommends for prints in target stores (which is what i have used in the past)
