I have run Mojo 15s, and like them. At the $125 price point, Tyrolia/Head bindings at 12 DIN or over work for me (170-175 lbs; 8 DIN). The Free Flex are good racing type bindings for skinny skis/hardpack.
I started using the Attack 13s last year on my "all mountain" skis, and liked the low profile, solid click in and feel while skiing, and light weight (for a 13 DIN binding).
At the $200 and over price point, I'd probably go for Look Pivots or Rossi FKS. Classic binding for a reason, and will always hold value.
Levelnine is a good shop, or Backcountry or Evo or The House (after getting ~8-12% cash back from any of the latter 3 via Active Junky). I bought my Attacks from Start Haus during last year's blowout sale...
