One time I sold a NIB unopened PSTII, and it went for just a hair over seventeen (USD, I think).
I was bidding on a Tomcat, because those devils are lovely but pricey. It ended up going for 104 American dollars, and it started at 20!
What's stupid is that there was another Tomcat with a "Buy it now" of only 99 dollars (American). I'll probably end up getting that one, but it's still a tad out of my price range. I'll probably work some overtime this summer, because I want to hurry up and get my Strad so I can buy more multitools!!!
