Price seems about right, but really depends on how it's loaded. They keep their value well. The 03' 20V had some issues with porpoising when the TAPS is set to anything above 4. You can fix the issue by putting some weight (or people) up front, but other than that, its a solid boat.
I actually have the Switch V 04' (essentially a 20V), and have been very happy with the wake, especially when it's loaded up above 1000lbs. The wake is a nice ramp, and has a decent kick to it when the TAPS is above 5-6. Construction is very solid, and it rides well in chop for a 20ft boat.
Let me know if you need information on anything, both my friend and I have owned this model for a total of 2 1/2 years, and could definitely give you feedback on any aspect.
