Finally, a mechanical keyboard that lets me type in one hand, and drink coffee in the other!
If it stays $20, that's a great price.
I agree, that would be a good deal. I have one like this (though with the "official" Maltron 5-pin DIN to PS/2 converter), and the switches are Cherry MX Blacks. Also, Soarer's converter
should work on it, I think, since it works on my two-handed Maltron.
/I paid a fair amount more for mine, but I was incredibly curious about them. Very, very light construction, lots of hand wiring of the switches using 30 gauge copper magnet wire, but quite well thought-out.
