Hey Leon,
I am green with envy! I had an option on one a few years ago but I didn't move smartly enough - someone beat me and I've always regretted it. Although I recall it being large and heavy, it felt very well balanced. The finish was of an exceptionally high standard and I am sure the optics were in the same league. A very desirable piece of kit indeed. What lenses are you planning to get?
If you go for it I look forward to hearing all about it! (Oh and by the way, you would be able to cancel your gym contract - lugging the beast around should keep you fit!)
Good luck,
Lawrie.
