I think the power level of the DSC2000.1d was its most appealing feature(at very reasonable cost). Plus, it actually does that number and maybe alittle more.
It's funny, I traded emails witha MB Quart rep just when the new Onyx series was announced and asked if they were planning a ONX2000.1d and he said "yes, it is in the design stage currently and will be released later this year". That was last year by the way. So, apparently there was a plan to offer a ONX2000.1d but, that plan was killed. Just about 2 months ago I asked another Quart rep what happened and he said they (Quart) wanted to be known as a SQ brand now and the DSC2000.1d series level didn't sell well enough. When I pointed out that they are still in high demand on forums such as this, he didn't seem to want to discuss the subject any further so I dropped it.
