The Lauderdale location is always bustling with activity. They do re-list older inventory on occasion as "new inventory" to re-ignite some interest/action.
Good stuff goes, junk sits. I have always felt that good stuff/deals go to inside people and the public gets to fight over the rest. The bidding process is very flawed and can be circumvented easily by sitting there in person with a checkbook with the broker on the phone with the bank.
My buddy bought a Rinker cuddy this summer, after a $900 tune-up and some elbow grease shining it up the boat appears to be a good deal. He ended up paying low book on it (2003, claimed 27 hours on meter). Boat hasn't broken on him yet (5 months/ 50 +/- hours).
