I have owned about 6 different brands of boats.. and my favorite is still the JWOutfitters Renegade. Its 8'6", perfect for flattish water and will row circles around any other boat on the market to this day. Mine is yellow top/gray bottom and broken down into the 4 pieces at the moment... but I am going to put it together and fish some ponds due to this high water of the last week.
What to avoid.. heavy boats with no usable features. Most your cheapies are made of steel and weigh in at 85lbs+.
What to look for, aircraft grade aluminum whitewater frames, a rowing position that is set forward to maximize your exertion on strokes.. oars that are longer so you are not digging to deep to try to get ahead, and a built in drop anchor system.
My Renegade is 42lbs without my 8lb mushroom anchor hanging off the back off the easy to use anchor system.
I will get some pics of the boat and truck I use for it up tomorrow.
