Meade 10"LX200 GPS vs meade 12"LX200 GPS

I have a Meade 10"LX200 GPS telescope and planning to buy a meade 12" LX200 GPS telescope, is it a good idea to switch to the 12" ?? Is the viewing remarkable better ?
and is the diference really great ?
Is there something I should be aware of, elctronics, optics or malfunctions ??
Please do responce, planning to start astrophotography.

Hey Freddy-
I've got the 12" and my buddy has the 10". We set up,
side by side. According to the Meade catalog, the 12"
draws more light. I really can't see a whole lot of
difference. We check out each others scopes all the time.
I had the LX90 prior to purchasing this 12". I CAN see
the difference between these two scopes. I need help
setting up this 72 lbs of scope on my tripod. He (my buddy
with the 10") is able to set his up along.
