Ok,
I found a crap lot of them It seems everyone and their mother makes them. This one guy outside of Niagara Falls area seems to be the best and cheapest too. I called him today and it's a small operation (he actually sews himself when work load gets heavy)
His product is better then the Kitty Mac. It comes with the pull down draw strings free and tidier set up at that. His screen is the only one that is fire safety approved (?) (important for you garage welders out there) Also good advice he told me is that all the others tell their clients to use a plastic PVC pipe in the bottom roll up chute. He said that is terrible. He said after the sun beats down on that for a few months it gets warped, bent and the screen looks like heck. Try pulling it out then..not easy. He said use a metal aluminum electrical conduit pipe.
Anyway if you want have a look at his temporary web page as the new one with video is being completed by next week.
