Harbor Freight is great for those one-time or minimal use tools. I wouldn't buy anything there that I intended to use heavily or professionally, but a lot of the odd tools I needed when restoring my Spitfire came from Horrible Freight.
I have a friend who buys a lot of hand tools from them because he uses them to make other custom tools and they are so inexpensive you don't feel bad about welding them or heating/bending them to odd angles for a single purpose.
