I collect tools....I hate needing a certain tool to complete a project and not having it, or worse having to stop what I am doing to go buy it and try to get focused all over again. So when I see a good deal on a nice tool or piece of equipment...I buy it..
For wrenches, ratchets, sockets I prefer the Craftsman Professional line. It is not found in store anymore but can be had off the Sears website. Occasionally you will find a "professional" model of a certain tool in the store, but not much of anything.
Besides an overwhelmingly large quantity of tools I seem to collect small engines. I like to grab broken mowers, edgers, or whatever off the street and taken them home and get them running. Rights now I have about 20 small engines of various sizes in the shop.
