You wont get any "nice" marker bindings for a good deal, so look for a deal on any brand binding. They are all relatively good quality. (Look, salomon, atomic)
A 12 DIN binding should be fine for you, I'd go for a 12 DIN, the DIN range will accomodate you as well as a junior binding, but there more durable. On this note, if you're looking at Tyrollia/Head bindings, go with the 12 over the 11, its considerably more durable. My favorite 12 DIN is the Rossi Axial2 120, take a look at my opinions of them here -
I don't have any personal experience with the Peak12 TH, but if you are going with tyrolia get the 12 over the 11. There will be some guys on here who can give a word on them, based on their personal experience.
