Suggestions on a decent cordless screwdriver

[magman]

Looking for a cordless screwdriver....no not a drill. Primarily used for r/c screws and such. Any suggestions thoughts would be greatly appreciated

Unfortunately I have some hereditary issues with my hands and when working on my r/c's it is quite painful at times continually twisting the wrenches....so, with hex bits like these....http://www.amainhobbies.com/product_...river-and-Case.......it should help make life easier.
