We have a favorable review (maybe two) of the GeoSat 2.4m
dish with polar mount, in the Review Department.
I don't recall any info on the Fortec 2.4
(... having trouble finding the version with the polar mount - call Sadoun.)
A while back, a new user got the GS 2.4 and had some problems.
If you find that thread, it has a happy ending.
Apparently the installers screwed up totally for the poor fellow.
As I recall, once aimed properly, it worked to expectations.
A number of members do seem happy with the 1.8m Fortec.
Many of them have it on the simple (non-motorized) Az/El mount
A few put 'em on H-H motors.
Haven't seen any reports of the 6' dish on the Fortec-supplied polar mount
I'd call up both vendors and get a quote for the beast, delivered.
It's possible shipping costs from one or the other would be the decision-maker.
