interesting, over here you rarely ever see the KRL Boxes, i actually don't recall ever seeing one, most guys seem to have KRA boxes, (what would be the classic 78 line in the US)
That said they market things differently here, the kra's aren't badged with classic or heritage on them, plus the fact that the krl's are more expensive here (a KRL1022 is $1600 more here) wouldn't be surprised if techs wages are lower over here too.....
Myself i have a KRA2411 rollcab with a KRA2410 Top Chest, they came as a package (that's the most common way box setups are sold here) with limited edition 'plaques' that fit inside the lid and on the front of the lower drawers, another common thing over here (not seen many like that on this forum, maybe they only sell them in Europe or the UK?) *i posted pics on the toolbox thread.
I'm real happy with it, seems well made and finished, though not having seen a KRL box i cant comment on the comparisons, the KRL,s do seem to look a bit sturdier and heavier, and better finished, but to be honest not much wrong with the KRA series, only thing that bugs me is the plastic drawer handle finishers, for the price they are i'd expect them to be anodized alluminium *my old box had alloy ones, not sure what model it was though, looked a lot like the current classic 60 rollcab though*
