Have to be careful with some things like lock picks. Various state laws can make having such things troublesome. Sure, most of the laws have something requiring the intent to commit a crime, but if someone gets the wrong idea, it's rather hard to prove that you had no such intent.
DealExtreme.com and similar might be worth picking some of that stuff up from. Mostly crap but hard to beat for odd screwdrivers and the like.
Oh, and add a "Don't show me things from stores that won't ship to my region lest I become consumed with envy and curse the very name of newegg.com" checkbox, perhaps :-).
That's a really neat collection and I'm going to have to put your site on the blacklist to make sure we have food here.
