I bought one of Dino's smart bases for my right bladed Bosch saw, just the smart base - not the whole setup. I just run it against a straight edge. It works well and does a good job. I also have a Porter-Cable 345 Saw Boss 6" left bladed saw that has dust collection, either a bag or I hook my shop vac up to it.
Since Dino doesn't have a variation of the smart base to fit the 345 I decided to make a temporary one until he does come out with one (hint, hint).
A piece of 1/4" baltic birch, some double sided carpet tape, a little cutting and we have an imitation smart base. It works ok, but I'm not sure how long or how well the carpet tape will hold things together.
