For me, it's worth taking the time to do it, and I don't factor time into the price of anything automotive related unless it's needed to get on the road. I, personally, like working on things, and would rather not spend the money because I'm frugal.
Do what you'd like, and if it doesn't work, do something else. You're probably not gonna die unless you're real careless with things.
