The design of the 2055 is superior to the 433 in which the 2055 is very solid, and it's casing is metal. I'm not saying the 433 is cheap at all, just the 2055 has won in construction design with toughness and awesome audio.
One thing to remember is that the Pro-2055 has had a lot of display failures. If you are going to pay that much I would get the BCT15 and even better scasnner than both them.
