If this is going to be primarily for this project, you could save some money by finding the sizes you actually need and then go on ebay and purchase just those wrenches and or crowfoot individually. Doing it this way you will save money plus the added benefit of being able to buy the nicer high end individually eg. Snapon. Having the complete set looks cool and feels good, but in all honesty I have only used one or two wrenches from each set. If you were a pro I would suggest buying complete sets, but for a hobby where money is a concern, just get what you actually need. You can add to it down the road a needed.
