These are generally poorly-made ouds, but occasionally one has potential for a decent student instrument; I recently came across one that sounded
surprisingly good and just needed new pegs and a new nut to be a pretty good student oud.
The pegs will need to be changed, they are generally from garbage wood and have an very steep taper (closer to a cone than a cylinder) that makes it
very difficult to keep it in tune. The ones I've seen recently also have a pretty much unusable nut made out of something that looks like balsa wood.
I would say if he would sell it to you for $80 and it sounds okay and the action is not crazy high, it might be worth it if you know someone who can
fix it up or are handy yourself and think you could do it. At $180, I think it is overpriced a bit.
