The people who used to make the Coleman brand now make them under the name Maxx and you'll hear mostly good things about them on this site. If its the company based in Florida who bought the rights to the name Coleman then that's a Living Waters product and I'd avoid it like a 3 legged chair.
There are a lot of good products out there. I like Caldera, D1, Hot Spring, Jacuzzi, Marquis and Sundance. Others have good things to say about Arctic, Artesian, Beachcomber, Bullfrog ... Go to the websites of each manufacturer and they should have a dealer locator where all you have to do is enter your zip code and they'll show you where their nearest dealer is. That ould be my first step.
But if it's a dealer that supports the product here then I should be covered for any problems right?
I bought the product from him, he is local and is responsible if anything breaks within warranty.
Although I think I can fix most of the stuff that could break myself. Don't think it's rocket science with my background.
