No EB head had PERS! LOL! The BD head originally had EVision, their equivalent to PERS, but, they took it out of later heads due to QC problems. Newer BD heads have the same system as the earlier Arnie heads.
The Smiler has fixed eyes, but, on later editions they're looking the other way.
Just the Hong Kong ACG edition has the smile head sculpt looking the other way. The rest should be the same.
I recently bought a Gremlins toys made by NECA that features a movable eye system with this ball that you can control the eye movement similar to Enterbay's Evision. I do find it extremely stressful because if the eyes aren't aligned during assembly it's not going to look right. Even if it is, if one of the eyes are stuck in the socket it will still screw up the parallel eyes.
