lol, you don't need 15
Well, the PC AT board is probably my overall favorite keyboard of all time. I have two of them at all times on my desk for my two computers. I only use another keyboard when I travel because it's too big to fit into my bag. I don't want there to be any chance I'll ever run out of PC ATs. I figure the main one I'm using now probably has about 25 years of use on it and still going strong. If all of them last that long, it'll probably take me over 350 years to wear them all out. Just in case I live that long, I figure I better be prepared.
Anyways, I guess I would be willing to part with one of them, but I wouldn't want to sell it for less than they go for on eBay, so just putting in a higher bid the next time one comes around is probably the best, unless someone else here has one they want to get rid of.
Ncbound10 on eBay lists them fairly regularly for around the $80 - $90 range, so keep an eye out there. Only issue might be the excessive shipping charges of about $30 per keyboard.
