Rule number one. Acquire skill before you acquire tools. Rule number two buy only those tools you know how to use, and suitable for jobs you'll actually do.
One of the best ways to waste money is to spend it on tools you can't or won't use. That's as true of bike tools as it is for overly powerful computers, or any other gadgets that get little use between the point of purchase and the scrap pile.
Start small, learn to fix flats, adjust gears and brakes, repair or replace a chain. That'll be 90% of what you need to know to enjoy cycling for years, and can be done with $5-20.00 worth of tools, some of which you might already own. Then you can expand your knowledge and buy more tools as your interest, time available, and budget dictate.
