I don't personally own a boat, but because I know how to work on boats I have a lot of friends who have ski/house boats.
Mostly up at Oroville, Engelbright, and Almanor.
Tige' 21 V is a pretty money ride. All the creature comforts one of the first to come out with a 'wake board' boat.
Sanger V210 is alright, but still a Sanger... Just don't have the quality the others do.
Nautique's are pretty damn nice (top of the line in my book) if you can afford one with all the features you want, you can't go wrong with one of these.
Malibu Wakesetter. Always been a great boat company. I havn't riden in the new wakesetter, but I'm sure if it's got the Malibu name on it you can't go wrong.
Bottom line. If you're going to spend 70k on a new boat (which is easy to do) you're going to get a nice machine. Just try not to put all that money into the stereo and get something that is really suited for your intended use. Trailers are probably the biggest thing I've noticed new boat owners get pissed about, make sure it's a nice one and if it says Ziemann on it DON'T BUY IT.
Have fun out there bro! See you on the water.
