Any of you guys use an OMNI Jig? Porter Cable dovetail machine? I don't want to spend the bucks for Leigh (?) adjustable jig, and I see the Omni's go for $150 on ebay quite often...16 inch variety. I do not want an adjustable jig, but I want one that is quick, easy, and holds both boards at the same time...I think this means it cuts tails and pins at the same time. Thoughts?
