Heard and read some favorable stuff on Goldtones--a lot of bang for the buck; A used Deering Goodtime might be a good move-otherwise, I think they are a bit pricey for what they are new.
Used is a great way to go; the old Aida "Mastertone" clones are decent; You also gotta decide whether you're looking open back, or resonator. Saga makes some inexpensive banjos too, but can't vouch for their tone. Saga/Blueridge has also reintroduced "Goldstar" banjos--a cut above the regular Sagas. Again, haven't played/heard one. My current 5-string is a Deering Sierra, which isn't inexpensive (but not up there with their top lines, or Stelling, Gibson, Sullivan, Wildwood, etc.). Try visiting banjohut.org. Lot's of good folks there (and probably "buy and sell" section too), and they know their banjers.
