Buy yourself the ZINN book and save $100s each year. I bought my book years ago and it paid for itself with my first repair when I saved $60. You don't need to buy a big tool set either. Just buy GOOD quality tool when ever your repair calls for one. Then you build your set slowly as you need it. I haven't had my bike in a shop in probably 10 years or more. Now I buy my frames and build them up my self to suit, as well as lace my own wheels. It's not rocket science. Park and Sheldon browns website are great for on-line tips. There once was a free download for Barnett's whole manual.
