Merkur also shows a Faively-style single-arm pantograph in their catalog. I don't know if its base can be adapted to the Williams mounting holes, but if I ever comes across a US distributor for their products, I'd be willing to get a pair just to see if they could be modified to fit. They do look a bit better than the sheet-metal Williams ones.
Failing that, I also toyed with the idea of fabricating some from brass channel and rod, but I've yet to do enough research to get a feel for how they're built.
If the Atlas ones are easy to obtain, all of the above is moot. I'd retrofit my E-60 and six Metroliner MU's if I could get hold of enough sets.
