I suggest we make a sticky thread for power tool suggestions.
This will help the cabinet makers among us to see some peer-reviewed tools before they make the purchasing decision.
Two items I just purchased:
Excalibur 40 inch sliding crosscut table for my table saw:
This one lets me make the BIG crosscuts with high accuracy.
MicroFence Circle cutting jig for my Porter-Cable router (it works on many other routers)
This one lets me make router cuts and circle cuts with micrometer adjustment. I don't know how I tolerated other circle cutting jigs...
