...as well as this
Rosewill Striker RK-6000 programmable MK with Tai-Ho Alps-clone black switches.

Unfortunately it has a BAE and 1x Backspace (did you know anyone still made those? I didn't) and a few other quirks, as (
this TechReport review) describes. But at $47.55 + 20% discount and free shipping (as it's over $35), that comes to... erm... just
$38.04 total.
I'd be tempted to order one just for the novelty of getting a new, full-size MK for such a paltry amount of dough, even if it wasn't perfect—but my wife already has enough big heavy objects with which to whack me around.
