Cant Decide.

Hey, I have to decide between two things, which I really need both of them. My front valve sticks alot now and I have a big leak that I cant find anywhere, were talking 150 psi in like 2 hours. I have the new valves sitting in my room. I could either re-bag the whole truck and get rid of all the problems and save on air... or! Both of my compressors just burned up and Im only running nitrogen. Should I re-bag it and just keep buying less nitrogen or get a new compressor and waste alot of air? I only have the money to do one or the other. Sorry about the big post but I had to explain it. Thanks.
