I agree that you should look on Craigslist. I just recently searched Craigslist for over a month looking for the right used kayak at the right price. My endless toiling finally paid off in the form of a 2013 perception pescador SOT. I got it for a considerable discount, and it seems to be everything I need in a starter kayak. All the reviews for this kayak are outstanding, and everyone agrees that it is great value for a reasonable price. I have yet to take it out but will post a review soon. Good luck with the search!
ps
Since you have a Tahoe, you could easily strap down the kayak, assuming it isnt over 80 lbs or so, with ratchet straps and avoid the cost of a trailer.
