[OT] Keyboard with ctrl, alt, shift, etc in the thumbs

[Pupeno]

Hello,
Does anybody know about a cheap keyboard that I could get somewhere in Berlin 
that has the special keys ctrl, alt, shift, tab, etc in the thumbs ?
Similar keyboards are:

http://www.maltron.com/maltron-kbd-flat.html
http://www.maltron.com/maltron-kbd-jtype.html

I am looking for an alternative until I can buy a Maltron keyboard.
Thank you.
