I get satisfaction out of making something from nothing. It's only partly about money. Every penny I save on something not fun can go towards something that is. More interestingly, I like taking something destined for the landfill, and making it useful. I make a lot of my supplies scavenging stuff from jobsites, and my gear has been patched with bits and pieces I've accumulated over time. Order of preference is make it myself - buy used - buy new. Power tools are an exception. I /can/ do mechanical work, but I'm not that good at it, and I don't enjoy it. It's worth it to me(fun money) to buy my saws and stuff new. If it doesn't work, it can go back to the shop, and if it stops working, I have a pretty good idea what the issue is, since I was the only one operating it.
