Basically, you need to know how to tune the tables on the machine regardless, so learn now and set them up properly and get on with cutting wood then check the machine every so often.
I feel David is right on the money and the machines of this caliber that hold in tolerance for life are about 2500+ lbs, so the rest of them including my own J/P which cost me $10k need the occasional tune up and check. It's just somewhat unrealistic to think that these machines are so sturdy that they cannot lose adjustment in a workshop let alone in transportation being in a truck driving over bumps, lifted and set down.
