No doubt there'll be more people pipe in re the PME - Lars is correct.
I know there is a another NZ forum member near Auckland - Jason - he might even be able to show you one in action. They can take a big scope - a number have 20" Ritcheys on them - that's around a 4m focal length and are capable of tracking unguided for a significant time with such a focal length. Its ability to 'home' is another significant feature. The mount ceases to be an issue in the imaging equation with the PME and is in my opinion worth every penny.
The main disadantages of the PME (ignoring cost) are the meridian flip and complete reliance on a PC for all operation, unlike its man established competitor, the AP1200.
