much better kayak in your dollar range the motor is a bonus that isn't needed but might be handy one day.
The ebay kayak you posted is not really worth the dollars, it has many things they have overlooked in making it. Drainage holes for a start. you could effectively be paddling a wading pool around if the drainage is not adequate, quite a lot of cheaper kayaks are guilty of this point.
