Don't know exactly where to put this little gem. Don't think it is worth a new topic. Have been so pleased with my advents since I built the bsc, wouldn't be inclined to exhange them for anything. Of course, they are and remain (until now) the unheralded bargain of the 21st century. But their auction prices have been creeping upward. See the recent A-4 result on Ebay. Item number:300254526569. Granted that the presentation was way above average, so too was the result. At first blush, the sale price of $617.67 plus shipping seems extreme. But in truth, I guess the adjusted new price of a new pair in 1978 would be around $800. Pretty interesting. Once again, thanks Pete for all your good work! Marty
