That was my intent, get me something bigger for all my tools that was on roller slide drawers and give one of my smaller units to my son and the other to my daughter or my dad. None of them have tools though. They all come to me for tools and have no interest in getting anything more than the bare basics for themselves. So yeah, all things considered, I'm just likely to add another Craftsman unit like my other 2. Those slides on those boxes work fine so long as you don't weight the drawers down to bad, and it's only the deep drawers I have to worry about, like the one that has my 3/4 drive socket set with 1in to 2.5in or so sockets with the big 3/4 drive ratchet and breaker bar. That drawer is pretty heavy and so is the drawer my Air Impacts and Air Ratchets. I'll have to make it work po man style.
At my age I wasn't going to spend a fortune anyway. I just wanted to go with the US General boxes at HF. Catch them on sale and use a 20% off coupon, they're not bad quality for what I'd use them for. I'm not in and out of every drawer 30 times a day 40-50 hours a week making a living.
