hi jorge:

i have been using a umax 2100 u with the transparency adapter for 4 years. lots of folks dis-
the scanner, but seems to work okay, haven't hd any problems ( knock wood!) every once in a while i do a search with google to see if anyone is still selling it, and once in a while it is still for sale for about $50 usd, the adapter is large enough to scan 4x5 ... and we got ours for $100usd ..
it isnt' a rolls royce, but it ain't a yugo either
