I decided for the $15 or 20 it costs to get it, if it gives you one more shop that you wouldn't have had anyway, it's worth it. If you already have all the shops you can handle, then it may not be worth it. I believe it has been worth it to me. As many MSC's ask if you have it, I don't think they would ask if it didn't matter to them in some way.
Time to build a bigger bridge.
