Hank - I'm sure glad you shared that with me - it's very different from what I have been reading. Seems to be a lot more flexibility than I thought - with pressure, etc. I also thought it was permanent stuff that you keep using over and over. Discarding it annually could be costly? And everybody talks about filters. It's not as complicated as the suppliers make-out!
One more question - can you run it slightly uphill by adjusting the pressure or does the field have to be level?

Keith - For years and years we used a gravity drip system with a 300 gal supply tank, 2" pvc supply lines and manifolds, and 1/2" pvc feeder lines with 1/8" holes drilled at various distances apart. It wasn't really a drip system, just "leaky pipes" basically. The drawback was lack of uniformity (fields not level) and we couldn't run long rows. It was very inefficient even compared to sprinklers. We don't have the water supply for that sort of thing anymore.
I have no experience with real drip sytems, with emitters etc. I've always thought they were only used on very small gardens and required a constant water supply with consistent pressure 24/7. I have also heard that they are nightmare to keep open, even with clean municipal water. I have an open mind and would appreciate any links or info -I have the well up and running but I want to take my time in selecting this system - may have to live with it for a long time! May never rain again in Texas. LOL
