Hi Christine and welcome to QB!
I checked on Pattern Review, which also has a very large number of sewing machine reviews, and I found a review for a Singer 7469QT. There's a small picture that's difficult to see; I'm not sure that it's the same machine as in the link posted by Amma. I'll put the link here anyway so you can check for yourself:

Even if it's not the same machine you're interested in, you may enjoy reading other reviews of similar machines. Good luck! :-D
Edit: I just looked at the review again to make sure my link worked and I think I was wrong, this may be the same machine. I was confused by the price the reviewer mentioned, $800, but she's in Australia and that's in Australian dollars. I hadn't read the comments at the bottom before, in those it's mentioned that the U.S. price for the same machine in October, 2009, was $299.
