OP, save your money.
You could get a used suspension setup, it's been done before, and no issues, it's also gone the other way as well.
You should get a new setup, I would recommend either coils + shocks or a full coilover system.
There is a Suspension Review Thread you can check out to help you decide.
NASOHC, also offers deals on Function & Form coilovers.
There is a seller on Honda-Tech that offers deals on Ground Control coils and shocks.
There is no rush, so do your homework, save your money and do it right the first time around.
