if you're looking for a quality old stock board to actually type on, it's a total crapshoot. i purchased a very large number of SSKs off of taobao as part of the SSKR project and about 80% of them were in horrid condition, with significant water damage, broken rivet positions literally hot glued in an attempt to keep the board usable, and so on. for me, this was fine, as i was purchasing for parts, but i would not suggest purchasing boards for use off of taobao.
