I have really enjoyed my Zaurus SL-5500. 
You can find them pretty cheap on Pricewatch. You'll never go back to a Palm 
OS. 

I mail-ordered mine. And besides the FedEx guy leaving it outside my door in 
the sun all day, it was a pretty pleasant experience. 

That being said, it depends on what you are in the market for, higher end 
handhelds I'd stick with the Zaurus, for something to get you by....I'd say 
you'd get most bang for your buck getting a Palm or Handspring.
