Oh boy are you in the poo with this decision. Man there are so many pro's and cons to this equation you could write a book about it. I am soooooooo glad I am not in your situation. Can you get them molded together into a HEQ5 Pro with Skysensor
Really mate this is a tough one you will find many pro's and con's to each. Is the HEQ5 New or second hand? Personally I would go the HEQ5 Pro, but you know I dont mind them, on the other hand the Skysensor is already a great working GOTO unit the v3 still has some bugs to iron out.
Whats the load carrying capacity of the HEQ5 compared to the EQ5 about 5kg? not really much there, maybe an ED80 next to an ED80
Okay go the Skysensor, I dont know anyone with one yet so you would be the first
Sorry can't be of any better help mate.
