Husky Bob has the right idea and there are still deals out there but you gotta go hunting in small towns and farms to find a lot of them. Here's a pump I found scouting out an old town and picked up for $175.00. It's been brushed a couple times but was in excellent rust free condition. So much so that the only thing I'm going to do is wash down the inside, lube the veedo-root and paint the panels up before putting them on with a new hose, pump handles and signs/globe. Bet I'll be into this one for less than $1500 when it's all done and said, and it'll look real pretty in black with silver doors, a custom GM globe and BelAir ad glass. :-)

(Body is very straight and only requires a sanding and paint job)

(Rust free inner frame just needs a wash down and pump removed)
