Scanner Master is very good. I think Scannerworld is good also. If I order from Scannerworld before 10:00 AM, I get the item the next day. They ship very fast.
The other thing I do for a big ticket item like this is just put the model number into Google and see who has the best price. There are a lot of good dealers out there. I always use my AMEX card and I've never had a problemthat didn't get worked out. I don't mean for this to sound like a commercial for AMEX but IF there is a problem, you just call AMEX and they take charge back the amount to the dealer and let me tell you...that gets the dealers attention!!!
Good Luck..you'll love this scanner!!
