I just ordered a Grr-Ripper push block set this morning from Jointech. They are on sale through today for a significant discount. Not affiliated with the company, just been waiting for a sale.
The price for the individual units:
Basic - was $49.95 now $39.99 Super (8 piece) - was $69.95 now $55.99
Both - $92.99
Saw a demo of these a woodworking show last year and read good comments on them here in the "rec".
Sale ends today - 8-29.
