I've got an OLD incra positioning jig (I think Rockler sells one like it now) and it is slow to use. The newer incras and the jointech jig are faster, but you are still moving the fence after every single step. I have a bare bones half blind jig, and it is fast and acurate for what it does. I also have a thru dovetail jig, nothing fancy, just fixed spacing, and it is fast and easy. For box joints, I use the Oak park jig, or a shop built tablesaw jig.
If you are going ornate, the jointech is awesome. If you're just making a lot drawers the Leigh DT will probably faster and easier for you.
