That really doesn't look all that special or as if it's anything out of the ordinary for the price of it, sadly.
Pretty sure that one's just the old (non-Costar) wireless Filco made non-wireless (though it still has vestigial battery compartments).
They do have a newer model ("Mechanic 2") which shares its form factor with the HEC Cougar Attack X, but with some differences in features:
PS/2 NKRO, macro keys (unusual with PS/2) with on-the-fly recording, game mode for windows lock but also with "Response Speed Boost" (probably some form of repeat-response tweaking, like on a Zowie and some other PS/2 keyboards), even a few media keys...the feature list actually isn't half bad, though the size and layout are rather unfortunate, and quality is unknown. Also, it's starting to show up on eBay now, so you wouldn't actually have to go to Korea to get it.
