I am also from Michigan,and feel the need to buy an auto knife since I'm now "allowed" to by the state!
I've owned different kershaws,ZTs and found them to be plenty quick with they're spring assist.
But I still want an auto!
Benchmade,microtech are top line and also fairly top price I believe
I'm leaning toward the Kershaws launch line. They are around the hundred dollar line and look to get good reviews!
And one of my qualifications in purchasing,they are USA made!
Good luck in finding what your looking for and have fun with it. Please let us know what you end up with,thank you...
