I just stumbled upon a steal for some planks to get me started in the touring world (K2 Shuksans, $25!). They were part of an ebay auction I did not expect to win (because of the ridiculous steal I got them for) and I am unprepared financially for getting them set up for a nice AT setup.
After discovering that my options for mountaineering boot compatible bindings where much more than just Silvretta 404s by checking out this site:

I realized I just need to ask what is available rather than search every model available. So if you've got some Petzl 8007's, Marker M Tour's or anything else in the dirt cheap range, I'd love to know about them.
