"In summary, like theossuary, I believe figuring out your niche stores will be beneficial ..."

As we figure out our "niche stores", I hope designers and entrepreneurs will study McMaster-Carr[1] - a site I found through the garagejournal forum that is an absolute joy to use.

Just drill down into any product category and you'll get a very simple listing, with full descriptions and very helpful diagrams of every single part.

If you need pipe fittings or hose clamps or rivets or gas regulators, please vote with your dollars at this site.
