Go to National Wood Products (2700 South and about 500 West. It's on the west end of the viaduct (sp?) and on the south side of the street. You can't miss it. Ask for Press, and tell him that I sent you in) to check out wood flooring, and see what you like. There are a lot of good pre-finished flooring now, but a traditional raw flooring that gets sanded and finished after the install is the best way to go. They'll tell you the retail prices while you're there, and I'll give you my wholesale price on any materials.
AVOID wood floor warehouse and other POS places like that. They buy all the mismatched crap from my suppliers that they won't sit on. They'll have a few odds and ends in a few hundred sq ft for .99 a sq ft that is worthy of a good camp fire, but the rest of their good stuff is in sample form and is actually coming from places like National with an additional %. Rip off!
Be cautious of buying anything online. Lots of factory seconds and other odd ball stuff the factorys dump off at a loss to get rid of it, and middle men stick it on Ebay or even Craigs list. I have a lot of customers that think they're getting a screaming deal on the crap they get, and it costs them 1.5-2 times the labor to install it and make it look half way decent.
Don't cut corners.
I have 3 other suppliers I can send you to if you don't find anything you really like at National. Ottley Flooring, SunPro or maybe MacBeath Hardwoods.
