I have been playing a Gold Tone open back which was made up from a kit for quite a long time now - its pretty good and mikes up well in the band.
I bought myself a??? th birthday present in December - a Gold Tone WHyte Lady with a long neck - what a banjo - although its takes a bit of getting used to.
Best advice is to try as many banjos as you can and settle for the one that you feel comfortable with -both price and playing.

Lots of good tunes played on an old banjo & my 1926 Windsor, despite its worn out look can still rattle along.
Good luck - keep picking
