If you only ski a couple of times a year and the bindings are still considered "current" then 25 bucks was a good deal if perhaps a tad short for your height. From memory that ski was a intermediate level ski. From the pic I can not say for sure, but it appears as if your binding is a fixed binding as opposed to a system binding. A system binding that is integrated to the ski is much easier to adjust to different boot sizes. A fixed binding may need to be removed, plug the holes, re-drill new holes and remount to the proper position. That can cost upwards of $50-75 as opposed to $25-35 for a system binding. If you are renting, you are paying $35+ so after 2-3 days you are ahead of the game assuming you already own properly fitted boots for your ability level. If you will still be renting boots IMHO you are better off just renting the whole package from the same place. Bringing boots and just renting skis is a better way to go. It will give you the opportunity to try different types of skis.
