Sedayne - I tried several fujaras when I was in Slovakia last summer. You need to realize how wildly variable they are - apparently identical instruments can get very different harmonics. The site you referenced lists qualities ranging from "professional" to things that just make a groovy noise to meditate to, and you'll get what you pay for (which will be rather a lot).

I decided not to get one as they're a one-trick pony. Groups that incorporate them in Slovakia tend just to use them for colourful introductions, they don't get them to carry the tune.
