I'm going to install some pretty soon, and am seeking feedback from you guys/gals. I think I want to go with solid, prefinished, 3/4" x 2 1/4", Oak (maybe "Toffee" or "Mocha" - it varies by brand)) and will staple it down (better than nailed I assume) above a crawl space. Any pointers or caveats that I should be aware of? I plan to buy a flooring stapler rather than rent...is something like a Bostitch the way to go, or will a less expensive brand (i.e. Harbor Freight) be OK for an occasional DIY'er? Where is a good place to source the flooring, Lumber Liquidators, Home Depot, Lowes, etc. or should I seek out a flooring specialist? Are most good brand names basically the same, or do you "get what you pay for" (i.e longer lengths, etc.)? For the floor itself, are the micro-beveled edges (some bevel the ends too) the way to go, or not? I've done a couple of laminate installations (for other folks) so I'm not a total novice, but just wanted to ask the braintrust before I drop the coin on this project. Thanks in advance for any advice you might have!
