you will also not likely find a dealer who will try to sell you a narrow, fast, low-primary-stability kayak, because they're pushing stand up stability and tall seating at the expense of everything else.
Read some threads on the forum like this one: viewtopic.php?f=1&t=249616&p=2284329
Many of the older boats discussed on this thread can be found for a few hundred $ or less.
also thread questions about new boats in New to Kayaking, New to Fishing and Saltwater, especially if saltwater is your goal.
A stable tall sit-up boat may be just the thing if you goal is short paddles in little water.
Some boats excel in the river, some for sit-up high bass-type fishing, some for traveling distance in wind - they're usually different qualities that make different boats excel at one or the other.
that narrow kayak thing, IMO averts the need for a tall seat, because it's narrow enough you can fish sitting up with your legs straddling the hull, which gives you really good stability - you only need your feet in one place inside the boat to travel.
