It's always a good idea to get someone who knows something about banjos to have a look at it or at least recommend a shop to you. The biggest problem (here in the UK) seems to be that guitar shops don't sell many and so have only one, which is on display and gets knocked about anf the nech warps. Similarly 2nd hand banjos have to be checked for warped necks.
Good luck with the banjo. I started a couple of years ago.
