Would this be a good value for US$100. I've read a few reviews and most of them said that the price-to-performance ratio for the 5200 FX series wasn't too great. Recently at a major retail outlet they mislabeled about half of the Ultra boxes with the price of the regular 5200, so I picked one up. These are new and in the retail package. It looks like a clerk was just puting the prices on and didnt pay attention.
