How to pick an EFII system ?

[Thor RV10]

My RV10 has only run on Robert Paisleys system. I have been very impressed with his help and service in the beginning. I rarely need help as the system is flawless. I would never want mags in my plane.

Moving to the technical side of "how to pick":

Are complete installation and operating manuals available pre-purchase?

Are there complete wiring diagrams available? Do the suggested electrical support systems pass a reasonable reliability review?

Dan, What are some manufacturers that you see who are giving you a warm fuzzy feeling?
