I'm going to bump this thread just to say that I have lots of SIIG Minitouch Plus JK-AB0211 (AT) and JK-APS311-S1 (PS/2) keyboards. These are the rubber-dome, non-clicky kind with rectangle Enter keys (there's a very clicky L-shaped Enter model but this isn't it). SIIG still claims these to have a "click and feel that typists prefer" but that sales copy is obviously held over from the original clicky Minitouch because the Minitouch Plus keyboards just don't click at all.
Here's the thing. These keyboards are unnecessarily expensive at $50 from SIIG but they do have a five-year warranty. Every few years a key falls off (usually Caps Lock which I use as CTRL) and I replace it under the SIIG five-year warranty. My last two replacements from SIIG now have a different feel, different key colors, and also a new OEM part number, "5100C" which I discovered is the very same BTC 5100C which is available from other resellers for 30% less. It's still model JK-AB0211 (AT) and JK-APS311-S1 (PS/2) but that's just a SKU I guess.
SIIG either stopped making these or they just changed the OEM manufacturer to this BTC outfit. These newer BTC-made models are all black (no grey keys). They also have a distinctly different feel, though they're otherwise superficially identical to the old MiniTouch Plus. When you buy the "BTC 5100" model you can also get the ivory-colored version and I also have a few of those.
Here's a representative vendor sample of the BTC:
