well i guess thats really up to you but ill assume that you wont find bindings that will fit on the kemper you have now. if you are starting out those $299 packages arent really too bad imo. getting everyhting together your first season is a big blow to the wallet. my only warning about the package deals at such shops is that the bindings are usually extremely low end and probably wont hold up to hard frequent riding. imo when starting out boot and binding quality are way more important than board quality. so once you decide to really invest money id start there then worry about a better board later.
