Excellent decision. I bought my 5 LTM cameras from an collector and they were shining like newly manufactured. I used Summitar and Summicron and their only competitor was Zeiss at their age. When you cut the rolls leader at home , it will be extremelly fast to load the camera. Now I am using a FED1g from 1954 and damn sharp. Try to buy your camera from a repairperson you mentioned and it will be fine.
