You could buy alot of tools for $1700. Mechanics wanted $1800 to rebuild the top end on a Bronco II I had. No way. I bought the manuals and did it myself (I am NOT a mechanic) for under $500. I did get a little something extra, though. A nice scar on my forehead where I clocked myself with the ratchet handle.
Seriously, if it were me I would consider doing it myself if that $1700 is true.
