Good luck with taking up the banjo - its worth the effort. I am not too sure about Eko banjos but its important to make sure that it is in reasonable condition. Make sure that all the tuners work properly and that the action is reasonably low ( a lot of cheap banjos have action set high to eliminate buzzes) and that the skin head is not damaged.If you are interested in Frailing then I seggest you get a copy of Pete Seegers book on how to play the banjo.

If you need any more info then get back to me - if you are in the UK I would be happy to getin touch as I have made quite a few banjos myself
