Has anyone in the U.S. seen or tested the TSL UHF RFID snap-on for the MC75 (P/N 1101-01-SO-UHF - http://www.tsl.uk.com/ProductMC70UHF.htm)?  Blue Star said TSL won't provide this to them in the U.S. market.  Another source said this is just a prototype and TSL is waiting for a customer before going into production? Thanks, Ken
