I purchased 2 of them today from a guy off of ebay for 100 each. I met the guy person to person and these things are new and in very good shape and they work. They sell for 300 each so I figured what the heck buy another while your at it for a future project. I asked him If I could put his email up here so if anyone was interested in buying one or 2 you all could contact him by email then just arrange it yourself. Here is the link to what he has.
