Those Ebay prices on new 898 units are nuts. New 899's sell for $999. Granted, the are some features that makes the 898 a little more preferable than the new models, but certainly not at the prices they are trying to get. A price for a used 898 will also depend if it's a HD model on not. The HD model has better sunlight viewing. I think a used price would fall somewhere between $600 for a non HD, and $725 for an HD model.
