I don't have an Axim keyboard, but I do have a Micro Innovations wireless keyboard (rebadged PocketTop)... I picked it up brand new off of ebay for $5... and there's plenty more.
Not only is it the smallest PDA keyboard that I've tried/owned, but it has the best ergonomics. I haven't been able to get it to work with my Axim Advanced/PPC2003 in portrait mode, but in landscape orientation it is a dream....
...unfortunately the landscape driver (NYDITOT) doesn't work with PPC2003.
