Rossignol axial/ look px (insert your din choice here) are just fine. Really when it comes to price they are all about the same, or sth if you want to spend a bit more. I would give other options but really you want something fairly common if you need to replace anything. I don't know about where you are living or what is best, so check your local shop and that should give you a good idea of what you should be looking at.
I used axail2s (12 din one) for about 30 days last season. They're are a little heavier than some other 12 dins but I found the durability on the axail2s to be pretty good. If you're looking at 12 din bindings the axail2 is probably your best bet. Otherwise see if you can get hold of the griffons from 2 seasons back with a bit of metal in, this place has them http://www.theoutdoorgearshop.co.uk/acatalog/Ski_Bindings.html
the axial 12/px 12/freeski2 120 are all the same binding just different rossi/look/dynastar branding. i would definitely recommend them, a bit heavier than some, but super solid and i've still got a pair that made it through 4 seasons
