Guys-
Right now,the best deal out there is the Husky ball bearing boxes at Home Cheapo.They're the same box in every way as Mac Tool's mid price series at about half the price.I don't have p/ns handy,but one of my boxes is a 5 year old 26" wide roller that I paid $900.That exact same box is in my local HD for about $500.
I've got Craftsman B/B(pre grip latch),Mac B/B,and Snap-On KRL boxes,and I like the Mac as well as any of the others.
Believe it or not,the box I like the least is the Snap-On.It's a 40" wide top and roller with full width drawers(36"?).Theres a lot of side to side play in the slides,not enough to cause a problem,but more than a box of this quality should have.I also have the locker on the side of this box,and I wish that the 4 drawers that are mounted in the bottom of the locker could be put higher,maybe about the middle height.Also,Snap-On needs to come out with a side cabinet for the KRL series that matches the height of the combo,but is all 12" wide drawers from top to bottom.They have a side cabinet thats the height of the roller,but nothing to add drawers to match the height of the top box.
You can get anything you want for the KRA series,if you want to spend big $,but the add-ons for the KRL are fewer.
