I just bought (Offer Buy it now) from Ebay for 65.xx including shipping. It seems light and small and from what I read, it looks like I will be able to track my vision2. Does anyone have feedback on this unit? the price and size seemed good. I made an offer for 60.00+ shipping and it was accepted quickly. http://www.ebay.com/itm/141617197784 If you have any experience, please let me know if I screwed up or made a genius move.
