sup man,
my suggestions would be to look into an msr (used to be walrus), they have a nice non-free standin tent lineup called the 'zoid'. great tent, awesome price. have done many nights in a zoid 1.5 with my backpackin bud.

also look at sierra designs. pretty much the same prices as the msr stuff, but with a bit more varied tent selection. their quality is outstanding and they revolutionized the non-freestanding (hoop tent) industry. companies such as msr are just now catching up.
if you're not interested in the hoop tents, still check out s.d., they have many more tents for all different types of campers.

i wouldn't get anything from REI for a different reason that most on here. it's too dern expensive! ha ha
most outfitters like that are sellin to a market that doesn't care about price (they do have great quality for the most part however)
i would also highly suggest the sierra trading post. bought lots and lots of stuff from them over the past several years to feed my backpackin addiction. gotta love gettin really nice stuff at almost half off
also, google for an outdoor equipment exchange website. i have had good results from them also (i'll try and hunt down a link for ya)
good luck with it, and let us know what you end up gettin,
malphrus
