With an OTF price matters a great deal in quality. I have a large collection of OTF, auto side openers, and assisted openers as part of my larger collection of knives. I have junk OTFs, moderate ($50-$100) OTFs, and expensive OTFs. As you'd expect, the higher the price the better the quality of the basic mechanical system.
The Desert Ironworks Sand Shark test is legendary. I've seen the same test done with a Harkins.
