Diesel, this is just my opinion, so take it for what little value it has.
I'm a home guy, pretty intensive, but on a rather strict budget. The HF 7 drawer side box is MUCH better than a Snap on KRA274_. Better built, 4 more drawers, ball bearing sliders, no shelf (some may like the shelves however), no door to get in the way and brand new at ~$200 it is very hard to beat. I've fondled the HF side box in the store numerous times on occasion, but just couldn't justify the $ for the limited storage it provided compared to a used 26" box.
I have or had a KRA274 that I bought pretty rough, spent a lot of time patching, fixing, straightening and painting. Intended it to be a drill press stand. When it was all said and done I felt the Snap On side box was just too flimsy for me to trust to hold my small drill press, so I got rid of it. Lots of time wasted, but a lesson well learned. If you want a box that matches and says Snap On on the front, by all means find a used KRA274 or the like. On the other hand if you are looking for a usable side cabinet and don't care about the brand or COO, pick up the HF one.
