I couldn't find Depo fogs for much less than the cost of OEM fog lights, and wound up with a TYC brand light I got from Rock Auto. It's not quite a perfect match to my OEM light, but the actual light produced is indistinguishable.
FWIW, I've had quite a few Depo replacement turn and marker lenses, and they've been almost identical to the OEM parts, aside from the Depo logo.
