I don't know how old you are but here are a couple things to think about. Tools are an investment. If you buy good tools you only have to buy them once. I have tools that I still use that belonged to my great grandfather. Even more of an investment are the skills that you acquire when you learn how to do things. If you have never built anything before it will probably be a pretty painful process however the skills that you pick up will save you money for the rest of your life. The number of people that actually know how to do things these days is absolutely sad and most wouldn't last more than a couple days without a store that carried everything they need. When you know what you are doing the only limit is your imagination. When I decided to get serious about my "hobby" I knew I had to figure out how to do things efficiently and cost effectively. My latest rack design that I actually finished last night holds 18 40qt tubs. It cost me $38 dollars to build. I still need to build two more however imagine what that would have cost if I had to buy them pre-built. I'm betting the shipping would be more than my entire build.
