Unless you're going to buy new and stay in warranty I don't see how anyone can own any metal toy without planning to work on it at some time. Even if you plan to farm out all your work there will come a time when something breaks at 0:dark:30 and mama isn't interested in waiting until you can get a mechanic on scene. Personally if I'm not under the gun I kind of like wrenching so its no big hardship but I feel the same arthritic pains that several others have referred to. (I'm MUCH younger than them though - just prematurely arthritic I guess)
I think its more about adjusting your timeframe. As long as there's an agenda it will feel like work. If I've got time on my hands I can make an oil change last all day and it will never feel like work. Working smarter not harder seems to come with age. I used to take pride in how much I could lift; now I take pride in how much I can get done with little physical effort. As far as lifting starters goes - get an MT39 and you will be able to lift two of them with one hand.
