I had a shot at a Microtech for cheap. It was an older model that would probably now fetch twice what I would have paid. Microtechs are expensive, but most of them are quality knives.
As for Benchmade, I think some of their stuff (not all) is HIGHLY overrated and overpriced. I'm not a hater, just call it like I see it. My brother and father in law have had TONS of them. I could probably get one for free, if I asked.
The Benchmade Infidel, in particular, is an over priced POS IMHO.....
