Cobalt and Regal are a class above the rest. I just traded my Regal in for a Cobalt. After 9 years it was in show room condition and never had a single problem. I was even amazed the batteries (it had 2) never had to be changed. The fast track hull is much more efficient than a standard hull.
Also go to Boat Test
www.boattest.com and register its free. Then look up the the models your are interested in. They will give mileage, speed and a detailed analysis. With the price of gas, you really have to consider the hull design. You may save on the boat, but the fuel could kill you. We are looking at $4 plus gas this summer.
Good luck!
