Tools. Not just having good quality ones (which is really important), but having the *right* ones. There's nothing quite as frustrating as having to use the wrong tool for the job. The first time you use the right tool after using a hack-tool for years, you think, "why the hell didn't I get this tool years ago?"

Food. It doesn't need to be super expensive Buck-a-Grape food, but eating food that makes you happy is really nice.

Kitchen knives. If you've got a couple good knives and a good stone, (and know how to use it) you don't need any more (I don't need any more) extra, crappy knives just get in the way.
