Hi Petr and
Agree with Erick, I have helped someone move a 14" lx90 (lighter than the Lx200) and it was heavy! Took 2 of us to get it off the tripod!
To be honest I would look at a Collapsible dob or a lightbridge unless you are go to permanently install in an obs, these big SCTs are not the sort of thing you just grab for a quick look. Suggest you go and look at one in the shops or get along to an observing night or star party to compare scope before spending a big wad of $$$!!
Remember, the best scope is the one you are going to use, and if it is to hard to get it out, its just won't be used!
