Ottawa Gamer has a nice review of the Pegasus Hobbies Technobridge.
The Pegasus line of terrain has long intrigued me. It is really cheap - this bridge was about $14 - but it is also kind of hard to find. I also had a hard time finding any pictures of it with a model near it for a sense of scale. From what Ottawa Gamer said this model is 8" long and 12" wide - you can fit two Rhino's on it side by side.
