Glad to hear it. Was thanx to Trouty that I got into Rush myself a few years back and have a few faves myself, like: Limelight, Spirit Of Radio, Earthshine, Totem, and my current fave, Faithless
Between us, we have mannaged to aquire quite a number of bootleg's of live shows (54 in total, and there are a number more out there), so if you wish, drop me / Trouty a PM, and I am sure one of us can sort you a DVD service 
I've got too many favs. to mention. Depends which decade your on about, lol.
I love faithless off the new album too. If you ever get a chance to read Neil's book Ghost rider do so, It's a great read about his troubles when his Daughter died in a car crash, Then his wife passed away shortly after. It was good to read how he got his life back together and then back to drumming.
