Rebuilding power steering box

Mine leaks like a sieve from a few places,I was gonna do the seals but after looking in the service manual,I decided it was worth it to buy a re-manned one just for the lack of hassle.$90 something and a $75 core charge from rockauto.com,but then I don't have a shop full of tools either.
Mine was sloppy anyway,if it was one seal I might have tried it.
I'd check the factory service manual before deciding.
