Shur-loc EZ frames. Once you get them, replacing the panels will be about the same price as sending the static frames out to be re-meshed. Except you can do it in house in a couple of minutes. I've only been using them since April (used to be all Newman), but they seem to hold their tension pretty well.
I still think Newman's are better, but if you're not staying on top of them and retensioning them, etc. (like I wasn't), then Shur-Loc EZ frames is the route to go.
