I totally agree with the sentiment, lavazza, but in this case, the user will be provide four possible providers for the service they have search for on our site. They will most likely go through the first provider's site considerably before deciding they are not suitable and wish to return to our website to try the other three in the same way. "Back" buttons, I did not feel, would be an easy way for them to do this. Opening each service provider in a new window seemed the best option for the user to me.
