What species do you plan on targeting? Are you fishing back water ponds, lakes and rivers? Or do you plan on taking the yak out on big water? Save up a little more and look for a wilderness systems, ocean kayak, prescador etc. These are better yaks. They can be found for under $1000 on kijiji.
I kayak fish kings religiously on Lake Ontario and Lake Huron. I quickly discovered that I could not cheap out on things...
Also buy yourself some straps and strap it to the top of your SUV. I used to strap down 2 Hobie Pro Angler series. These are huge yaks and it could take it no problem. If you don't have a roof rack use a couple pool noodles or foam blocks to rest it on.
