I have a Dyson (with cord) from 6 years ago...I think it's a good vacuum...which was about the same price as they are selling the HSN TS.
I, personally, would not want a cordless, which I assume you have to charge? Just me, without any facts here, just seems it wouldn't be as powerful.
But I do love my regular, plug in Dyson...I could refer to the book, and advise, if you wanted the model#.
If weight is an issue for you...I can assume by looking at the TS it's lighter than mine, which isn't too heavy, but "normal" vacuum weight, and moves around easily, smoothly.
