I think your 18"s need to go for at least $200 less than 19" stocks. I sold my 19"s for $2k shipped. $1800 shipped should a fair price value to market conditions. you won't sell for that price here in this site, maybe try ebay for your asking price. Just an honest opinion. Good luck none of the less.
