JMH,
I have a buddy that has a 19' sea hunt w/ 150 Johnson. I have fished on it once and it seemed to perform like any other c/c. It's a wet ride in windy choppy seas, so get rain gear. The 150 is plenty of power and his came with a 5-star trailer.
He has a brother-in-law that has a 22' sea-pro c/c w/ hd. top and wants to sell. The boat is a 96 but has only 250hr because he lives in GA. and fishes in Va. B-mail me if you want specifics. It would save you big$$$ and be a step up as well.
As far as new C/Console boats it would be hard not to go with a Parker. My dad has had an 18' for years and has repowered twice, but the boat is still in good shape. It's a no frills fishing machine, w/ no thin plastic hatch covers etc.
MY 2 cents,
Bill
