I went with the TCI M2 Kit and power rack and pinion steering.I really like the power steering and it aint that much more work put it in.Just make sure your pump pressure matches the rack pressure. I used a GM power steering pump,and TCI units use a TBird rack ,so I had to get a pressure reducing valve for my
pump. GM puts out 1300 PSI, whereas the TBird unit calls for 800 PSI.Anyway power is the way to go.
