Older Boats with surf shaper

I keep going back and forth on buying a new boat (I work part time for a dealer so I can get one at wholesale) or buying an older boat and using a shaper. Payment wise it will be about the same but one will have a 20-year payment and one will be a 10. My deal would require me to own it for two years before I could sell it. So I start leaning towards used boats when factoring these things in.

So I was wondering what boats you have ridden on with a shaper and which ones put out legit surf wakes or crappy wakes. So I can weight my options and decide on which road to take.
