If you plan on making a lot of different dovetails and such, get an Incrajig. I have one that is a combination table saw fence and router fence that I use on my modified table saw/router table. There are so many projects that can be done with this one simple fence system that you cant go wrong. I dont know what that model is like but I had a dovetail jig from seers that was made from plastic and it didnt hold up well when using it on hardwood and would not hold the wood tight enough and caused me to ruin a few pieces of expensive Walnut when the wood shifted while cutting it with the router.
