I agree with what Southwind previously mentioned...if you know what kind of boating you're looking to do it'll be easier to narrow down what you should be looking for.

Where will you be boating?
Are you a weekend boater? Are you going to want to launch your boat on a holiday weekend?
Are you gonna want to be able to take a bunch of friends with you?
How fast are you gonna be happy with?
Will you be doing regular boat maintenance/fixes yourself or will you be taking it to a boat mechanic?

In my opinion, this stuff should determine which direction you go in when buying any boat...but it also can help figure out which hull/style/setup will work best for you with a v-drive.
