For under $300 you really only have a few options. Either you could go for a pair of Barons from the 2013 season or older, since the 2014 Barons will use the EPF frame, you should be able to find these at a reasonable price. Or you could go for a pair of BCA Alpine Trekkers, this would allow you to keep you current alpine bindings, so saving you some £££. If you're only going to be touring a few days a season, Trekkers will do the trick, you do hear Trekker 'horror stories', but they aren't too bad just always carry a crew driver, screws and some duct tape.
