Protech is one of the, if not *the*, top name in production automatics. With any Protech, including the Godson, you are getting a top quality production automatic. Is it worth it? If you want one of the best switchblades in on the market, then yes.
Since switchblades are fairly complicated (compared to manual folders), you have to pay a bit more to get quality. However, if you want to spend less, I feel the Boker Magnum AK74 Automatic series is pretty good. They cost 30-50 bucks and are pretty decent. They are the bare minimum in terms of useable quality, though. I have one and it opens VERY strongly (lots of kick), and decent steel (AUS-8), and feels great in the hand. However, it has some fit and finish problems including a safety that doesn't stick in either position, and I don't think it will last as long as a Protech.
A Protech is very worth the price, but do not buy it unless you are sure it will be worth it to you.
Why is Protech (and other high-end automatic brands) so expensive?
Higher-quality materials, and better fit and finish.
When you press the open button on a Protech, you will notice how smoothly and strongly it opens. And even if you think it feels very similar to a cheaper automatic such as an AK74, then you will notice the difference in cutting performance as Protech uses better steel. And if you aren't a steel snob and don't care about edge retention, then the biggest difference is that a Protech will last longer than a lower-quality automatic. There is a lot more in an auto that can wear out out break than in a manual. Also, because of the better materials (including handle materials), and fit and finish, a Protech will look better (especially when looking at details) than a cheaper brand.
A couple brands that compeat with Protech are Microtech and Dalton. Check them out too.
