Well those associated costs pretty much go for any set up you get nowadays. So it's just pricey to get into it. Then again, it's still way cheaper than having to by a ski setup for backcountry riding.
Voile isn't exactly cheap with their costs, so I think you are going to see more companies go with Karakorum for some of the basics. The K Clips are worlds better than they chinese hooks from Voile anyway. At least imo. There could be a little improvement with them, but overall they are pretty damn fine. One of the two best $50 purchases I made last winter for my Split.
