Well, if it makes you feel any better, I've got two K75SA's and one K75SA Pro. Neither of them have given me any problems. Very fast and very reliable in my experience.
Anyway, another really cheap board that I've have good experience with is the Shuttle AK32 (see Box#8 of my specs). It's built on the old reliable VIA KT266a and will except either SDRAM or DDR. These can be had for about $50-60 new or you can find them for about $30 refurb'd. Mine is a refurb from newegg and it's one of the best boards I've bought this year.
