Which brokers expose order book data?

I found this indicator:http://forex.asolutions.ee/

He asures that order book data is "very visible". Smells like scam?

I don't know if this is what you are looking for but i received this in a mail once from Global Prime:

"There's many advantages of working with Global Prime including the fact that we are the only broker which provides trade receipts on any trade taken which show which bank took the clients trade."

not bad, worth a try....
