Thanks, what motor are you using, didn't see it mentioned. I am changing from a 1m steel orbital dish (8Kgs) to a Gibertini op125 1.2m aluminum dish, I just weighed it and it's about the same (8Kgs) on a Motek sg2100 motor, but mine is ground mounted and very,very sheltered. I also bought the polar mount in case I needed it though. I think I read somewhere that laminas no longer make the polar mount, but may make a small production run if enough people wanted/ordered it.
Let us know how you get on
