It won't be easy, but you're going to have to trust that I know my own life better than you do. If I should go to the time and effort and expense to repair unneeded tools properly, where would I draw the line? Fix tools I have fewer than three of? Fewer than five? How about the 80286 computer w/ 30 Mb hard drive I found in a back closet. Pay to have that upgraded to current specs, or learn computer repair and do it myself?
I don't mind advice that misses the point, but I don't like it when it comes with a superior attitude.
