a "which camera should i buy" thread

[mfopen]

I recently went down to target to get some things and took a look at their cameras... Originally i had a Nikon N75 in mind, but then i saw they had the Canon Rebel EOS T2, which(in my opinion is an excellent camera), all i had to compare with it was the Nikon N55 though. The N55 looked all blurry and bad focusing, but i thought that was just because it was a display...I plan on taking outdoor, indoor and sports shots, well pretty much all around i guess. How does the N75 stand up to the Rebel EOS T2?

Also i hear sigma lenses are cheap? (specifically the Sigma 28-80mm F3.5-5.6 HF AF Mini Zoom Lens)
