Do you want the best price, the best quality or the best value for the money?
Are you willing to wait for a good deal?
Are you willing to work at restoring some great old tools?
Do you want to learn how to make your own tools?
I started out buying junk at the big box stores of my time which were Sears, K-mart (Kresske then) and the local hardware store. Most of them gave poor results and wore out quickly.
Then I started buying better tools at yard sales, antique stores, estate sales and auctions (e-bay of yesteryear). Some were in good shape and ready to use, but that has changed over the years as the tools got further away from the original user and passed through several abusive or neglectful hands.
By then I had learned how to maintain my tools and refurbish the ones I found in the wild.
I would love to be able to buy new Lie-Nielson or Lee Valley tools, but I have a wife and four kids to feed and clothe.
I still get the most bang for my buck at antique stores, yard sales and flea markets. I like to handle the tool, talk to the seller (not that you can believe anything they say, but just to see how much they know) and bargain for the best price.
If I were in a hurry to accumulate a set of tools I would go to Highland Hardware, Lee Valley, e-bay, some of the old tool on-line sellers that have a good reputation and the Midwest Tool Collectors Association swap meets every year.
