Another door op. provider that's good is Fermator. Make sure you buy the European style, not Robusta from Columbia Elevator. The version Columbia sells has sturdier hardware, unlike the cheap Schindler 3300 plastic door rollers that cracks in two all the time. The electronics are decent, but older versions like the VF4 are prone to electrical shorts and fires. That's been fixed in newer models.
Overall, I think Fermator is better than GAL in terms of harmonic operators (which I hate, except for extra large door openings); however I like the Delta/Monarch Nice900 (modified for GAL and NA market) powered MONXT operator better then Fermator's electronics. The MONXT motor and drive can fit onto some Fermator ops. as a direct replacement; meaning, if you have trouble with one provider, you can always try the other.
Don't dare fall for that GAL MOVFR knockoff "smooth operator" crap from SEES, genuine MOVFR is king compared to their knockoff.
