Dawg is right and they will stand behind it. Nobody likes to be the one with the "only one to have this issue" problem. I'm not sure from reading this that Zippers picked all of Mark's components. Research, talk, inquire, network. Whatever you have to do to be convinced that everything you do is properly engineered and perfected is a buyers responsibility. Buying something before that is called "buyer beware". If some salesman at Zippers talked you into something, they'll at least get it straightened out or refund you. I'd give Dawg a chance to find out what's going on. He seems to know these guys pretty well and should get a straight answer for you. You'll still be in the "trial and error" process though. Maybe it'll be right, maybe it'll be closer. If you can't deal with the process anymore, ask for a refund. Hoist!
