Hi Ezra, I have used James Klein's J.P. Beck kits and they are great! The pre- inletted areas are precise and fit tightly, Jim selects nice wood for his kits. His castings are very good as well. In my kit James included some samples of his stains and Homers to. Jim is indeed a gentleman and will talk with you over the phone if you have any questions, I would highly recommend using all of his stuff including his browning solution, it is the very best and used by makers such as Allen Martin and Jim himself, enough said!!
Good Luck,
Bart
