I am going to take the plunge and get a 797C2I SI. It will be the version without the maps and I will buy a 2008 south card. Should I buy one off ebay for around $850 or buy one from a dealer for the MSRP of $999. Obviously the dealer route has its advantages. Service after the sale, a place to take it back to if it is broke, and you give them money they hand you the unit. With ebay, you hope it isn't a refurbished item, you hope you get it, and if it is broke when you get it, most of them will tell you to contact the manufacture. I have been buying on ebay for almost 10 years now and only got the shaft once for about $30. But ebay is more and more scams then ever was. What do you guys think? Is it worth it to save $100? Or has anyone bought one from ebay that can recommend a seller?
