Rocknaks mostly lists highly maintained boats(there right in my town), and I've noticed their prices becoming more attractive to buyers. The T34, there's also a 79 Pearson for the same price, and this 79 Mk1 Sabre, asking 35 and it just went on the market.
The Sabre has a pretty fresh diesel, not too old paint, lightly used sails, newish dodger, and it's clean as a whistle. I bet it doesn't last long and it will likely sell for 30k, maybe less.
