http://www.ebay.com/itm/121859181974$150 for what looks to be:
2x M0110A (tee mount Alps)
1x M0115 (AEK)
1x M0116
3x AEK II, at least 1 with ISO layout
plus 4–5 rubber dome boards (looks like some of these are the type with Alps dyesubs, or they might all be crap) and several mice.
Everything looks somewhat dirty, so all the switches might be crap, and the keyboards might or might not work. At the very least this is great source of Alps keycaps, and possibly some nice orange/salmon switches from the M0115/M0116.
Price isn’t too amazing, but also isn’t bad, especially with free shipping. Might be able to make the seller a lower offer for a subset of the boards.

Also, a good choice for anyone who wants some PBT keycaps for a Matias ErgoPro: that ISO-layout AEK II has the required extra-wide keycaps for the leftmost column of keys (backtick/tab/left shift – note it’s this keyboard’s 2.5u right shift cap that fits the Matias ErgoPro left shift spot).
