I know it might be different than what you had in mind, but I really like my Original Incra Jig. It's not a porter cable, but it's also not priced like a porter cable. I think for about $110.00 you can get the positioner, a fence, the right angle fixture and the dvd. I would say that if you're dovetailing anything wider than maybe 6-8 inches, then one of the other jigs might work better. Just thought I would throw that out there. It makes a pretty good router fence too. I upgraded from the positioner to a Ultra positioner because I really like how it works.
Hopefully this helps and doesn't muddy the water.
