I also think it is a great idea, but start shopping as soon as you can, go look at a lot of them if possible. I bought off Craig's list and when you find the one that has been well kept, maintained and cared for it will stand out from the rest. You can also get a feel for what the prices are for the units your looking at, they can and do vary by thousands. I bought from a private owner and that saved us a lot in taxes out here in Arizona, private to private no tax. I did look for a short time at dealers, but felt like they were way over priced and I wanted to deal with the owner of the unit and get a feel for what they were selling and why.
