The quality minefield! For the sake of brevity, heres a precis. They all come from China or Taiwan, and one very expensive one from Germany. The ones that come from China and Taiwan then all come via the UK or the USA. If they come via the USA, they are expensive because the American Revenue grab a bit of tax and then our Revenue do the same. Peoples take on quality is subjective and depends on the purpose fro which they are making pens, practice, personal use, boobytrapping for the mother in law or selling commerically. Frankly, experiment and have fun. UK importers of the USA stuff, Pencrafts.co.uk or theturnersworkshop.co.uk or the archive of poor quality and outdated kits, which is currently residing at Turners Retreat. Stiles and bates havent really got a clue about pens and isnt worth bothering about but they have some great wood. There are ebay suppliers, they tend to use one of the largest Chinese suppliers and although they come from the same company, the quality varies depending on what the kit is. Have fun and form your own opinions depending on what you want to get out of your pen turning hobby. Best of luck!
