This is a well designed jig that should hold up well. I like the router base insert idea. The insert glides along the template fingers to give precise control for the bit to follow. This jig is designed to let you cut your tails & pins with fewer steps than other jigs. The only reason to purchase a different jig would be if you wanted one that would allow you to adjust the finger spacing. But this jig will do most drawer jobs etc just fine.
