Look at the Akeda, Leigh, the cheap PC jig (for half blind drawers). Go here for good reviews:
About the Akeda - "It may be the best all around performer and the best choice for woodworkers who don't want to mess around with a dovetail jig, don't use the jig every day, don't like reading through user's guides, yet want to produce a variety of flawless joints."
The Leigh is good but has a LONG learning curve, I use the Akeda much more than my Leigh.
Also the WoodRat jig allows one to mortise and tenon in addition to making small dovetails, the use HSS bits that mimic small hand cut dovetails something that no other jig can do. While I do not own one it is on my list (after a Shepard Tool jointer plane kit, 36+ inch belt sander and a ***DREAM*** Woodmizer portable sawmill).
