i drive an RC8 and im the same way - tried to go cheap on my tools.
Almost all my tools are harbor freight EXCEPT FOR HEX DRIVERS
DO NOT GO CHEAP ON HEX DRIVERS - DO YOUR SELF A FAVOR AND GET THE MIP 1.5MM, 2.0MM, AND 2.5MM - THATLL BE ALL YOU NEED FOR THE RC8
it will cost you more in hardware if you go cheap on your hex drivers, - but for everything else just go to harbor freight and go nuts
