I've had 2 Matco boxes, the first i bought in 88. I still have it at home, 25 years of professional use at roughly 8 different shops and NO issues at all! Never replaced a slide, all drawers work great. (damn sounds like I'm writing a CL ad ). As far as tools go, I have both SO and Matco, each has it's pluses and minuses. The bad thing now is that Matco mostly rebadges their stuff. Whenever I see something on the Matco truck, I find it online for half the price. As far as impacts, I have all IR, Matco rebadges these as well, they're great tools. If you're getting a really good deal, I wouldn't hesitate to get anything from Matco, just don't pay full retail.
