I believe that is just a matter of them not updating their list after the release of 1075 and 1100 that came to the table later.
Thanks! I had assumed the various models would have been released sequentially if not simultaneously. But, prompted by your reply I did a little research and found that the 1035, 1055, & 1090 came out months before the others. So, I suppose it's safe to assume whichever of them I can find a good deal on would work.
