Dear clc,
A lot of the choices in kayaks will made by your size and body type before you even set foot in a store.
If you are 5' 11" and under 200 pounds you have dozens more options open to you. If you fit that body type you can easily find an Old Town Otter used for $ 350.00 or less.
It is a sit inside kayak but depending on where and how you want to fish it may be perfect for you. I have a buddy who has one and a small folding cart he built. He can take the kayak, a couple of rods, a small soft cooler, and all the gear he needs for a day and just grab ahold of the bow line and tow the thing 3/4's of a mile to a Gamelands pond.
I know that because I fished with him and had more trouble myself carrying a float tube, fins, lifevest, fly rod, and fly gear than he did with his towalong rig.
The Otter is about 10 feet long and rather lightweight and easy to handle when it comes to mounting and removing it from a vehicle. It is by no means the only option but there many of them out there and people often sell them with little use of wear and tear. You won't run the Yough in one, but the moving water in most parts of PA is easy with it. My friend uses his on lower Penns, and the West Branch of the Susquehanna with no trouble at all.
If you can wait a while check out the Demo days at Blue Mountain Outfitters in Marysville. They usually have something the first weekend in May or so, and you will be able to check out a variety of different models and styles of kayaks.
Edited to add. A pontoon is another choice but better suited to lakes and ponds or when traveling with a partner or two on moving water. That isn't because of any kind of safety issue but rather because it is world's easier to move upriver in a kayak than it is in a pontoon. You could put in after work on the Susky, paddle a ways upstream and fish down several times on a summer evening. If you put in with a pontoon someone will have to get you back to your launch point. I know because I own a pontoon.
Good luck,
Tim Murphy
