http://www.ebay.com/itm/251863360705?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AITCorsair k95 for cheap. Needs fixing, so you might as well do it if you’re going to change the red switches to something else. Strongly suggest not bidding over $32 (for $50 shipped). When owner claims ‘couple of switches not working’ and then says ‘some keys will not produce symbol’, I suspect damage is a lot more than a small localized spill. For all you know, all 120+ switches are corroded by orange juice and must be changed.
This is the kind of thing I would like to buy and mess around with, if only I lived in the USA.
