After looking on ebay and other on line retailers as well as reading a lot of other on-line data, I got worried about not having a warranty (not because I am worried about it breaking, but more as a just in case lifeline). As you will find out, not buying from a qualified retailer will void your warranty and most of the on line people didn't offer much of a return policy. There is a pretty lengthy post from a guy (do a search on Abe's of Maine) and hear is woes. I'm not saying you will have any issues, but it was worth my peace of mind to haggle with a storefront dealer. And yes, I said haggle. And yes, I paid more than you will online but not much if you factor in some type of MACK warranty, shipping and handling charges etc. Besides, I got to take it home right away and start tweaking my 2500. Also, the unit will be good for many years and that factors into pennies a day. That's my 2 cents.
