sdcfan18: Well, the CS450 is one of the younger Dual models and the semi-automatic brother of the fully automatic CS455. It was introduced around 1989 (shortly after Dual had gone from Thomson to Schneider) and together with the CS455 represented the best model of the entry-level range. In contrast to its smaller brothers CS435/430 and CS415/410, which I wouldn't really rate as hifi class turntables, the 450/455 is pretty ok, if you don't expect too much - and it can sound pretty nice, when coupled with a good cartridge. It definitely isn't one of the really good Dual turntables, though - and hence it's not much sought after, either. So I can only hope you didn't pay a lot for that thingy.
Oh, and a thing I should mention: Whatever Dual branded device of recent production you might see nowadays (except turntables), doesn't really have anything to do with the old Dual company and its successors anymore. This already began during the Dual/Schneider era, as Schneider got more and more into financial troubles during the 90s and finally sold the Dual brand for anything but turntables to Karstadt, who subsequently used the Dual brand label for priceworthy far eastern import ware like ghetto blasters, micro systems et cetera.
Well, and for the Stanton cart with D71EE needle: That should do for a start, although I wouldn't really regard it as a very good match - but I'm not much a fan of the sound of the 500 series Stantons and their T4P siblings, anyway...
