so far i haven't found a cheaper place, although they do ship components inside the continental U.S. for free.
This forum's Multitools for Sale and Miscellaneous for Sale areas sometimes have people selling parts for great prices.Another thing I found is a source for the Paladin Telecom components. SOG doesn't sell them on their website, nor does Paladin, as far as I can see, so if you wanted to add a punch-down tool or hook to your Powerlock, etc... it is possible.
