JJ is on the right road.. bite the bullet and install the diverter valve.. by the time you buy 4 high pressure ball valves or 2 three way valves, add the cost of the plumbing them in, it will cost more. the next thing is you will need to have access to all the valves and have to make sure that the proper ones are opened and closed (can see a big mess of broken pieces and oil all over if some one uses the machine and does not know how to operate them) with the diverter you can mount it any were and keep it looking clean..
