I use their tools all the time. I buy their cheap stuff and if I use it often enough to break it, I replace it with Snappy or MAC.
Though due to the economy I no longer have a MAC guy on my route and am accumulating a pile of broken tools that need replaced.

Go ahead and try to ruin your first toolbox. If you use it enough to NEED another box, plan on spending more money.
FWIW I have 3 snappy boxes, 1 mac box, 1 mac cart and 1 cornwell cart. I paid well under 2k for all of them combined. They were all purchased used. The oldest has been in my possession for 18 years.
