I play it a little. I don't own one but a few of my friends and family do, I just fiddle with it a bit when I go home. I can play guitar and piano, so it wasn't too crazy for me to intuitively play around with.
If you want, maybe just tune your guitar different and learn a few scales to start. After that maybe buy the cheapest Oud you can get ($125ish I think) and see if you like it.
If you want to go for the gusto on a quality Oud right away let me know, I'll give you some info after thanksgiving.
