Hi Phil and welcome to the *NUT HOUSE*, aka "Striker's Place".
As has been said many times before by all including me, is *APERTURE WINS*. The final choice is yours alone, and it all depends on what you want to do in this facinating hobby and how deep your pockets are!
ps. It also helps if you're in with the local weather gods.
pps. I think you'll find that the LX200's have bronze gears, while the lower cost units have aluminium. L.
