Hey Johnny, welcome to the site!
I’m a primarily guitar player too, with some fingerstyle experience. I found that it translated pretty good over to banjo and I picked stuff up pretty quick. I think playing different instruments helps to improve your overall skills, although I can’t really explain why. Maybe it’s technique, I don’t know. The only problem I ran into was splitting up the time between the two.
Hopefully some guys with buying experience (I borrowed one) can give some good advice on what to look for. Good luck, they are fun to play!
If you’re having problems with the site, post up any questions. Maybe one of us can help ya.
