I've never seen Cornwell around here... from what I understand through reading these forums... they are a good tool tho.
Just for a reference point tho... you can buy a similar set from NAPA, over the counter, 6 days a week for about the same money. If you wait until it's on sale.... probably 30% less than that. Comes with an over the counter lifetime warranty so you don't need to go tracking down someone's route truck to get replacements. The price the pawn shop was asking was outrageous. The MSRP is completely asinine.
