try Butler Creek. It's rock solid and available for something like $70-$80/each.
I already said I'm not interested in BC, BTW I already have a ATI folder & I want to steer away from anything else that is plastic ,not that it is crappy or anything like that, I just want the real deal.
I would have bought a BC but I don't like the plastic. When it is folded up I find that the end of the stock is right in the way of where I like to hold on to and is a little awkward feeling.
