I have the Porter Cable jig and was also concerned about the max board width since I wanted to make a large dovetailed box. I found there is a supplementary instruction manual online that shows how to do many things with the jig not covered in the manual provided with the jig - one of them being dovetails on an unlimited width board. The jig can actually do a lot of neat functions - inlaid dovetails, making hinges, mitered dovetails, box joints, etc.
That being said I've also turned towards hand tools for making dovetails. The options for panel size, layout, etc are endless, and I like being able to say I cut them myself. Plus, I don't think it takes much longer to lay out and cut the dovetails on a box by hand than it does to set up the jig to cut them with a router - except when you are doing many drawers with the same setup.
