I ordered one piece from him, and I really wish I could say I had a similar experience to those above, but I didn't. It wasn't a huge deal, but mine took between 4 and 5 weeks to ship and the cast was far from good. It looked like a really rushed job, FULL of air holes, and required a lot of clean up and modifying even to get it to fit together.
I wasn't really upset, it was my first resin kit build and it gave me something to do, but after reading so many high praises from different people, I am a little bummed I didn't receive something of higher quality. Especially for what I paid, and the waiting time.
I will add that he was always pleasant in our email exchanges, and I have been considering trying another one of his kits FWIW.....
