If anyone reading this buys anything from sysmaster, you are a FOOL. I purchased the 7000 and had a sysmaster engineer on the phone for weeks. It never worked. I returned the unit and now sysmaster wants to keep 90% of what I paid for their fees. Needless to say, my company is filing a classaction lawsuit. If you are interested in adding your name to the suit, send an email to email@example.com. You may share in the $$ judgement.
