AFAIK, there aren't any. I would not recommend getting a newer Cherry PCB mount board as they seem to be much lower quality than early ones. The two G80-3000 boards I bought with Clears are really flexible and don't feel good to type on.
It's worth the effort of desoldering the switches on a GOOD plate mounted board (like a KUL for instance) to turn them into ErgoClears, but I would recommend also adding "trampolines" (little silicone balls from IMSTO in the tubes) and stickers at the same time, while you have the switches open. Also shaving the mold lines on the stems and lubing them will improve the feel a lot, too. Then they become amazing to type on, IMHO, and doing it all at the same time means you only have to desolder / resolder them once.
I own two ErgoClear boards with SA profile caps on, one with stickers and one without, I can tell you that they DO have an effect. They stabilise the switch tops enough to be noticable with any profile cap, but markedly with tall keycaps like SA. And plate mount is also worth having.
