The Rhodes19 is the Mariner19 and I think was the O'Day19 (for only a couple of years). Theoretical hull speed is less than 6 knots.
The Rhodes22 is an incredible boat but it is unlikely that you'll find a one in your price range.
Its LWL is 20' which would give it a theoretical hull speed of 5.99 knots.
It's not the easiest boat to trailer, rig, and launch. It has 9 stays and when you raise the mast you are also raising 300 square feet of sail (uses a mast raising system). With motor and gear you'll be towing about 4,000 lbs. Its trailer has an extension tongue but can still be a problem at some ramps. Most people only trailer it in and out for the season or for an occasional vacation trip, as opposed to everytime they go sailing.
I don't want to discourage you from buying a Rhodes22. I looked at most of the boats on your list and bought the Rhodes. It's perfect for my needs but may not be for yours.
