BTC 5100c. $52 (I included the shipping). 80 key. Black case, grey modifier keys. The rest are black. Dunno if it's foam & foil or dome w/slider, but a search on the forum says probably dws. It's supposed to be a very good dws, tho. "Poor man's HHKB."
Which is now mine

Flytech Carry I It's a BTC 5100 with "your mileage may vary" key switches. $65, including shipping. BAE + full sized backspace.
Zenith ZKB-2. One key removed to show yellow Alps. $170 with shipping. Average condition.
Northgate OmniKey Plus. "White switches." $125 with shipping.
Northgate OmniKey 102 Ultra "White switches." $125 with shipping. Looks like the seller's got SEVEN, in addition to these two.
Zenith 163-0092-02-00 Looks brand new. $150. Wiki says SKCL yellow, but also shows an older logo. Might be a good idea to ask the ebayer to pull a keycap.
