In my neck of the woods used SP101s are going for well over $500, thats when/if you can even find one. Heck I havent seen a new one in quite awhile. The extra you pay becomes miniscule over time. I got mine last year for $470 used and I consider myself lucky. Good luck, my SP will be in my safe for a very long time.
