I agree with TJ and Count...what's wrong with Dagger?
Hobie has done an amazing job in the past couple of years and the new Agent is a great boat, not to mention dry. I just bought one and couldn't be happier.
If you are going to post a statement (especially to a newbie) like that, please have the courtesy to state a reason why you think that way.
We all have opinions...but not all of us have reasons for those opinions.
I agree with the "river runner" comment as far as boats go. Learning in a displacement hull boat (the hull on most creekers) is actually a bit better for your learning curve.It will help your stroke technique get better since you can't rely on the edges of the boat to help you turn it. If you learn in a displacement hull and then go to a planing hull(the hull on most, if not all, river runners and playboats), you'll be a bit of a better paddler.
Good river runners are the Jackson Fun series, the Wavesport EZG, Wavesport EZ if you can find one used.
Go into a shop and talk to them. There are some great ones in the Front Range. Also check out the Mtn Buzz sway section above for used gear. I am guessing that if you are guiding this summer you don't have a ton of cash to spend on gear but you might.
Lastly, take a class. All of your friends will want to teach you to boat but what will probably end up happening is you will pick up their bad habits. Always good to learn the basis for something instead of just doing something...
Just my $0.02. Good luck...paddlin' is addicting!
