    Good vacuum pump for hobby?

    As some already know refrigeration is a hobby of mine so I don't do it much. I'm in need of a good vacuum pump for occasional use and am curious if anyone could recommend one? I looked at a few made by CPS but don't know where they rank in the scheme of things.

    Also is a digital vacrometer really needed or is the one on most manifold sets good enough? I have a set of Yellowjacket II brute gauges as well as a CPS R134A set.

    My main projects will be refrigerators which have refrigerants that are very sensitive to moisture so a good vacuum is important. I have all the time in the world when doing this so speed isn't an issue but I want a good strong vacuum.

    Thank you for your time and as always all comments are welcome.
