I saw the earlier on KVR but was waiting to view the youtube tutorial before posting.
Many years ago I remember seeing English folk duo Bob Fox and Stu Luckley in a pub during the Cornwall folk festival. One of then was playing a Portuguese guitar and I remember being really impressed with the sound. It was about the time "Irish" bazoukies were becoming popular but the Portuguese guitar sound seemed to have more depth.
29 euros is just outside my $30/25 pounds "jump on" it price range but I think this high on my wish list unless something in the tutorial warns me off.
