Model 1 is kinda hit or miss...there have been some folks here less than happy with their stuff, and customer service.
I bought 2 kits from them...one had a pretty serious problem, but they fixed it with a minimal amount of hassle in about a week. The other was fine from the box, and that rifle shoots great.
Others haven't been so lucky with the customer service, though.
Another place to consider is J&T...they're a little more expensive than Model 1, but there are a lot less folks here with bad stuff to say about J&T than there are Model 1. I bought a J&T kit, and it was very nice...better finish than the Model 1 kit, for one thing.
