Another Glll suggestion from the middle of the country.
The XA doesn't have a very impressive rangefinder compared to the Larger cameras. It is also completely battery dependent.
Barnack was the designer of the original Leica. Very compact bodies and thread mount lenses. 1st model wasn't interchangeable
Leica copies can be Russian(FED), Japanese(Tower,Canon,Nicca+more) Russian lenses can be hit or miss
