I've recently been through the same decision-making process, for exactly the same reason. Although I dive in relatively warm water, there were many times over winter when a 5mm plus a hood wasn't cutting it, and I had come to hate the lack of flexibility in my elbows and knees with a 7mm.
I ended up grabbing a DUI TLS350 second-hand from the US, for much less than I could find them used here (very little second-hand market in Aus). It's my first drysuit, so I have no basis for comparison, but I love it. I was a little worried about teething problems with drag, overheating, seals, buoyancy, etc but have had no problems at all.
I actually wish winter had lasted a bit longer so I could have used it more!
