It was for just such a job that I ordered a toggle-switch size punch from Greenlee. These days, when I need such a box, I MAKE one from a Nema 3R gutter, and attach single gang "Bell" covers as needed.
For the receptacles, I use a Dremel to cut 'Decor" openings in the cover.
Availability aside, I'm pretty disapointed in a lot of the "Bell" stuff out there (including similar stuff of other makes). I don't like the way they mount, screws seem to jam or strip too easily, parts corrode together, and the cover gasket never seems to seal.
If things keep on the way they are, I might have to mount a small milling machine in my truck
