Got my $10 Data911 TG3 BL82's in the mail today. After converting it to Dvorak, I don't think I put all the keycaps on right, because it's super hard to type on. One has the thin plastic sheet (and is older, according to the PCB). The other is newer, has actual rubber domes aver the cherry blacks, and is newer. Both are in excellent shape. A complete bargain at $10 shipped from ebay. hanks to litster for the tip.

I'm going to take this rubber dome sheet completely off, it's super annoying. The red backlight is really pretty, though: Much better than I expected.
