We used one of those for my work, it was neat we had it set up so that you scanedeverything in and then could always go back and look it up, kept all the hard copies off site..
I used Quicken. You can set up your own catagories, like engine, transmission, interior trim, exterior trim etc. What I like most about it is you can run reports and see where your money went....I guess that would also be a bad thing too.
