One can pick up a Data I/O 29B and Unipak II off eBay starting around 
$100USD (ish) Make sure it powers up before buying it with no error 
messages showing. Seller should show picture of the display with the 
model and revision code showing.

There is a very good support group on yahoo groups:

They have an extensive file system and I have some Data I/O stuff too here:
