I restored a few visibles and a clock face last winter. I broke even at best on all of them. I probably over restored them as I treated them like a classic car and finished them that way. My biggest expense was not the parts it was the paint and materials. You use a lot of stuff up to do it right. With that being said if you are doing it for yourself and have the knowledge and tools, I say do it yourself and it will probably mean more to you when its finished. The lesson I learned is there isn't a lot of money to be made on restoring pumps. So if you are looking for the cheapest way out find one you like and buy it.
