I bought a refurbed Abit NF7-S (v2) from newegg a year or so ago when they had it for $30 (when it was something like $95 new). It was perfect, came with pretty much everything.
Most of the time I hear people complain that they don't come with everything (box, stickers, manuals, cables, etc) that the retail one obviously does. I don't remember hearing about a lot of DOA boards. How much is the retail version of that mobo you're looking at? If it's really a steal, I'd probably go for it.
