Union offer lifetime warranty on their baseplates and heelcups, I think some other companies offer lifetime baseplate warranty as well? My mates old Burton Missions also have lifetime baseplate warranty, do Burton still have this or any other brands?
I'm pretty disappointed in my Union Forces. When I received the board and bindings from the local shop I didn't take the time to look over them properly, when I got home I had a good look and noticed some imperfections. There was a drop of paint on the heelcup that looked dodge, and the glue keeping the foam on the highback was letting go in one area. I couldn't be stuffed returning or exchanging them since they are gonna be used anyway and went to the slopes soon after anyway. Even after doing all the screws up as tight as possible by hand they started coming loose and the heelcup moved on the first day of riding. I didn't have a screwdriver with me so had to put up with it.
I guess as long as yuou get a reputable brand and the right binding for your application then you can narrow it down to a few and then just go on looks or tech or whatever excites you.
