Unless restoring guns is your hobby, and the time it takes to do it yourself is irrelevant, it's best to follow the advice given by those above.
Having said that, restoring/building guns is my hobby, and I have brought back guns that should have gone in the garbage bin. As a result, I am now able to own and shoot some very fine guns that I could never have been able to afford and purchase outright. Good thing my free time is, well, free.
I'll also end with, there is nothing worse than a bad restoration (which you see all too often) so think long and hard about the choice.
