Hello,
What are you talking about? I have a 20 gallon and I'm using it. It's great man. That's why I love VHOs sooooo much. I do want MH though. But not now. Not until I get my job and know where I'll live and build my 300g tank, at least that's what I want, space permitting.
I bought it from Reefers, swithced owners to Brian a little while ago. Very nice nice guy. But they had a bit of finance problems and their site now looks interestingly weird:

I don't know of any one in Canada selling it. If you want one, I can see if I can get one for you but not now, unless it's super urgent. I forgot how much it was but look up Niche Engineering, that's the manufacturer. It's a few hundred dollars US that I know.
