Most of the tools needed to remove crank arms & freewheels are just little specialty sockets, bits, & adapters. Things you can get on ebay pretty cheap. What you really need is the big wrenches, breaker bars, & vise in order to utilize them. If you want a decent vise & really can't afford the high prices most places charge then check out Harbor Freight. You can an entire set of metric wrenches for the same price other stores might charge for just one.
