Any good or familiar keyboards in this pic?

There's a guy near me selling a lot of keyboards:

I e-mailed him to post info on the back and this is his reply:

Focus Electronics Model FK6200 S/N 00622007

PC Concepts Model KWD-203 Model SK710

The second one down from the left looks interesting. Also, the bottom right one may be mechanical due to the 101-key layout.

Anyone recognize any of those? Thanks.

DEC LK201. A truly awful keyboard.
