Reliable as a rock but not the most powerfull thing in the world. With an added turbo or a factory 93.5-94 IDI turbo they will outrun a stock 1st gen powerstroke. If that truck is not rusted out it is well worth the asking price. EDIT, they really take well to a 75/25 mixture of WMO so the fuel bill is next to nothing.
I have a 94 IDI turbo that has been cranked up. Stupid thing snorts pretty good even with a 6500 pound trailer on the back. I'm thinking of turning it down because it is somewhat of a fuel pig.
