Been about 10 years since I last looked through any Dr stuff. They are good stuff but IMHO they didn't quite have the quality "diamond sharp/bright image" that the Swaros, Zeiss Victory or any of the S&B optics typically do. But I want to say they weren't priced up in that range either, usually somewhere between say a Zeiss Victory and a Conquest of comparable size.
I'd put them on par with Meopta and other former eastern bloc stuff available today,
