I just recently added a tortec ultralite rack to my bike. I want to post a bit about it because I had a hard time finding pictures, or much information about it previous to my purchase. It's probably difficult because it does not seem to be widely available in the US. I purchased mine from Wiggle for a little more than 30 dollars. Shipping would have been a real killer, but it's free if you spend 85 dollars (which I did).

The Good:
I realize it's probably not touring strong, but it does seem to be a very good commuter rack. It's cheap, simple and relatively light. The hardware is stainless steel.

The Bad:
I had some issues with the seat stay mounts. They want to bend and attach on the outside, unfortunately my bolts are on the inside of the seat stays. I had to reverse them and flip them upside down to make it fit. It's solid as is but the hardware is difficult to access.

There is nothing at the bottom of the rack to hook my panniers to. I used long M5 bolts that stick out far enough to hook to. (thanks to grim for that tip)

Hopefully this is helpful. Here are some detail pictures for anyone interested:
