depends on how much of a pinch you're in! if the p12's and the 1260's are still good you'll just be breaking up a happy home if you go down that road. the rossi axium120 from 04/05 is a good binding if you can find it, should be much cheapness too.
ronin do a colour called merlin which is purple. looks pretty good in the catalogue but i've not seen it in the flesh. pretty much all their styles come in it.
karma if you're looking for a 'hardass' ski. PE if you wanna relax a little. the graphics on both are pretty sick but the karma will break your wallet more!!
as far as i'm concerned( i've only used the sm8's once on a test) these boots rock.
the sm10 is a stupidly popular boot and there's not too much difference between them.
if you're gonna go for rossi bindings, go for last years model with the pivot heel if you can cause they did away with it this season and its not as good!
