6 Inch Bench Vise at Sears. $40 or less,varying
Closest equivalent Ive found is close to 100 bucks.
The vice is 49.99 currently. Add 1 small item such as the below, or a screwdriver to hit 50 dolalrs.
I happened to have 15 dollars in surprise points for 50 dollars in tools, so my cost was 35 bucks.
Then I earned 15.50 in points off of it, for a total effective cost of 20 bucks (depending on how much you value funny-money as... since 100 bucks funny money on a 100 purchase is NOT really "free")
YMMV but SYW has 10 dollars in points for $50 in tools so $50-10 is your worst case scenario.
