I am planning a DIY 10yds concrete slab on my side yard and I am almost ready with compacting, grading and setting up the skates. Now I need some concrete finishing tools - I have round end fresno, magnesium bull float but need a walking groover. Tried local homedepot, sunbelt etc but couldn't find a walking groover. Any suggestions on where I might find in San Fransisco bay area, CA?
