Just get anything to get started. Then spend some coin and get a real nice one. A Bell Kit would ship easy....and the price is right....accomplish both at once.
The Prust is on my radar as is the Gardner one that Tim did a review on. Andy Banjo in the UK also make a modern fretless banjo as do Deering but I'm not sure what to think about those.
Anther option is for me to wait until I come to the USA, next year and then bring one home with me as a "souvenir". That's a long time!
Meantime I'll carry on with my starter banjo that I have put minstrel strings.
