I have two of the LR32 sets (one for my house and one at my cottage) as well as a 1010 and 1000. I also have two of the Kreg shelf pin jigs.
To be honest, for drilling shelf pin holes I vastly prefer the Kreg jig. It's way faster to setup, almost as fast to actually drill the holes, extremely compact, and an order of magnitude cheaper. And, as someone above mentioned, it's possible to use it after an install is in place.
The only thing that isn't so nice is you have some dust you need to clean up later, but it's not a big problem.
