I'm beginning to get more serious about looking for my first kayak, but I will be doing so on a fairly limited budget. I'm 6'2 and hover around 270 or 280, so I could stand to lose a few lbs but I would at least like to find a kayak eventually that I could safely use at this weight. I know that this also means a higher price tag. What brands, models, etc would you all recommend for someone of my stature who is looking for his first fishing kayak? What should I reasonably expect to spend on a solid used one that will fit me?
