The goverment surplus sales company, Government Liquidation, has a lot of 18 Tempest Dovetrons up for auction. Check out their website at: www.govliquidation.com. Event number 794, Lot number 520. It is a sealed bid auction, opening 2/11 and closing 2/14. I would guess the gear will go pretty cheaply. Their setup is similar to Ebay. Jack WA2HWJ NNNN
