Asus makes great boards, period. The P3B-F is still one of the best boards to use for an Intel platform, esp. if you plan to O/C. I have built 17 systems for people around this board alone, not a single problem. As with any motherboard though, a lot depends on the core logic chipset, and even a high quality motherboard cannot make up for a crap chipset.
Yes, their TS does suck, but as previously noted, they release BIOS updates constantly. And as with all companies, your first line of contact should always be your reseller. If you buy from a skanky reseller, that's your fault. And if you have a good reseller, and still can't figure out how to resolve the problem within their return period (usually 30 days) but fail to return it for an exchange, then that is your own fault as well.
