I ran across this while visiting Cruising Anarchy. Taleisin is indeed for sale for $175,000. David Jones has the listing and there is another Lyle Hess 30 footer for almost half the price---with an engine on the same page. No explanations given for why the Pardeys want to sell her. Despite all the comments regarding their emphasis on simplicity, one can't take away from them their accomplishments.
