Right on!!!!... or Craig's List. Can't tell you how many tools I've "borrowed" on Craigs List. Buy it cheap, use it, relist it.Got a nearby pawn shop? I guarantee that they will have a used shop vac there for 1/3 the price of new.
I call craig's list the community tool shed.
When I refurbished my keel.... I found an engine hoist for $75. Had to put a new jack on it for $40. Sold it for $125 when I was done and made $15 profit.
I just did a search on my local Craig's List for Shop Vac and got 81 hits... and I don't live near a big city.
