If you can forego the clicking, SIIG has a nice, new miniature keyboard in stores now. It's their third version of mini keyboards. Myself, I like the second version Minitouch Plus, which appears on eBay from time to time (one seller was selling a lot of 10 for $25 each, this is a $40 keyboard). The other folks here love the hugely expensive and rather unattainable original SIIG Minitouch.
Also, Adesso has revived their line of miniature keyboards. Their older keyboards were good since they weren't just laptop keyboards without the laptop. Their new keyboards you'll have to try them out to see which one you like.
