I'm just talking out of my head rather than from experience. I periodically browse craigslist just out of curiosity. I very rarely see 14"'s for sale but very often see 18"s and fairly often see 22"'s. Right now, there's an 18 for $175 stating that it has never been used. I , personally, have not seen one of the spectacular deals at Walmart or elsewhere but I read of it happening on occasion. I am guessing when I say you have to be at the right place at the right time. Good luck with your decision!
