I think I saw the same advertorial that the original poster did, and whilst they made the machine sound great I am not convinced.
The other Silver that was shown working did not look as if it had a great stitch - as the demonstrator held it up and noted that the machine was known for excellent stitching the stitches on the fabric looked distorted. This could obviously be a tensioning issue or similar, but the fact that it looked 'off' when doing a simple straight stitch (and when she looked at it she didn't say - oh, my tension is off let me do it again, as she did with other items like selecting the wrong stitch) did not give me confidence.
The 'quilting' Silver also did not look to me as if it had throat space much more significant than that of a normal machine. I haven't looked up the details so perhaps I am wrong on that, but it was my impression.
And I echo the others in that whilst it is nice to have a selection of stitches, there is no way you would use them all.
Whilst I understand your enthusiasm, I would stick with a 'normal' machine for the moment and wait until you can get to a shop or a show where you can actually try the machine out before handing over a significant chunk of money. The difficulty with QVC-type shows is that you can only see what you are shown and have to take an awful amount on trust. And sewing machines are a very personal choice - even if the machine itself has no issues, you may still not like it. If you look at any of the threads on here talking about who has which sewing machine you will see that there are many differing views, and all equally valid because people like and dislike different things.
Let us know what you choose, but I would advise waiting for a 'hands-on' opportunity
