Hey Jim.
I also have that HF 44" box, on top of my roll a way Mac Tools bottom.
I like it a lot. Suits my needs quite well.
That 44" box sure has gone up in price since i bought mine.
I only paid $315.00 for it, when it was on sale.
So i can't complain, at all, what tool box's are costing, in this modern day and age.

The new 44" is deeper than the old one. I found that out the hard way. Had an older bottom box and bought a new top last year...Had to buy a new bottom and sell the old one. Still got about what I paid for it...
