While I was in Colombia this past summer, it was impossible to find peanut butter. Then only place we saw it was in Bogota at the supermarket, and it was about $9 US per jar of Jif. You could however, find peanuts fairly easily, so what we did, was to use my buddies coffee grinder. Worked pretty good, just took awhile due to the small size of the grinder(could only fit a large handful at a time). We didn't have TV though, so it was at least something to pass the time.
If you use the grinder for other stuff, make sure you clean it out good. My buddy used it to grind peppercorns, so even though we cleaned it out pretty good, the first batch of peanut butter had a bit of a kick to it.
