I have a 2007 dodge last of the 5. 9's and I've been looking for a Box/programmer the last couple of months. For a while I was leaning toward the VanAaken C5 because of the adjust on the fly and open software but lately it looks like they are heading downhill fast and I don't want to purchase a box if the company isn't even going to be there in 6 months for tech help. My second choice has been The Smarty because of the positive results you guys are always talking about and I do like all of the features it offers so now I'm just wondering where to find the best prices for a MADS smarty. Any feedback is appreciated.
