I really like my Canon T2i, I actually upgraded from my original XT. I'd vote for Canons personally...really you can't go wrong with a Canon or a Nikon at this point. The real expense can be the lenses... You always want one you don't have. Usuallythe base lens they offer in the kit is good for portrait type photos or indoor stuff, but doesn't have much of a long distance zoom. You can always start out with the kit lens and as you better determine your real needs get a better zoom lens. I've only got the 18-55mm IS kit lens but have a zoom 75-300 that I can borrow and I really like that versatility. I've been really wanting to get an all in one Tamron 18-270mm, I t would really be the only lens I would need... But it's like $450 used.... I'll keep it on my wish list.
I'd second the idea of going to like BestBuy and picking up a couple and see which "feels" better and then kinda let your budget decide which model.
