Line bindings...  sucked and will continue to suck.  Great concept but shitty construction.
Marker bindings... sucked in the past but may prove to be decent this season.
Salomon bindings... ultra light weight, break too frequently but there are ways around that by replacing the titanium tracks with steel ones.  Brakes will break but I haven't come up with a way around that... find a ski shop that understands the dilemma and will try to help you out (Pinewski's.)  Their new binding, the sth16, should be an ultra improvement!
Look bindings... heavy but withstand abuse really well, but I do know that A-Ron and Drew broke theirs.
4FRNT bindings... heavy again, but they also withstand abuse really well.  I have broke the steel plate inside the heel but Drew has had two pair and hasn't broken them yet.  It has a self adjusting toe piece that will continue to fit as your boot wears out from urbans.
Just so everyone is aware, most companies are cracking down and becoming more stingy with warranty situations.  Starting with the smaller companies and then becoming more prevalent in the corporates.  You need to find a good shop that will work for the warranty on your behalf (Pinewski's.)
