Just my 2 cents
I have many dovetail jigs, the HF type works very well and is easy to setup once you remove the errors from the jig..with just some shop made jigs and wood blocks...
The real Advanced to the HF type is you can do the front and the sides all in one pass of the router bit....or you can do the back and the sides the same way, that's makes the drawer/box very strong unlike the normal way with the just a slide in back part and a nail or two...
If you set it up right you can do the front and the back in two clamp downs , that's a real time saver.
