I strongly suggest you avoid the cheap SSR's from China that are on ebay. Stick with quality manufacturers like Crydom.
That said, it is perfectly acceptable to use a 240VAC rated SSR on 120VAC.
Another suggestion would be to look for "zero crossing switching". This isn't necessary, but it does make the SSR's job a little easier.
FWIW, I'm an EE that specializes in power conversion. That doesn't mean I don't screw things up on occasion, though (there's a reason I picked "MagicSmoker" for a name
).

Would there be any advantage to using a 240VAC rated SSR vs a 120VAC or variable rated SSR? Similar to using a 40A ssr that would create less heat than a 25a SSR when used to control a 2000w 120v element.
Might have to try an find some Crydom SSRs, they ain't cheap though
