I've just recently got the TIS. It's OK but sketchy on detail. I think detailed how-to's such as the ones posted here with photographs, are far better. Bentley usually takes a similar detailed, graphical approach so it may be worth the money. I'm a bit disappointed with the TIS. So I've been bookmarking the best how-to's. Thanks to everyone who contributes. If only I could figure out how to upload pictures I'd be able to contribute too.

Anybody want a TIS?
