For the 7 gal AGA MB setup, I bought the aquarium itself at King Ed's in Burnaby, but you can get it cheaper now at J&L ($65 I think). For the retrofit CSL, I scored one from King Ed's... I saw one there last time I was there a couple weeks ago as well. They're hard to find here in Canada as CSL is now pretty much nonexistant so they stopped producing them.
I got most of my setup info from:

I can post a pic of my setup later if anyone's interested. Gotta take some pix.
