Frank,
I recently bought a Grizzly 0555 w/riser block after doing a search on DHBP and other web sites. From the multiple reviews I read, it has the reputation of being a great value. The riser block installation was easy enough, and from my limited experience the saw has been working great. The hardest thing I've cut so far is a 8"x14" decoy body from laminated 2x10 (am using the part normally discarded to make a jig for future bodies), and even cutting the 9-1/2" thick top profile was like sawing butter. I did switch to a 3/8" 4 TPI Lennox blade for cutting bodies as the factory blade was not very good.
