Drilling tanks: Pros/Cons

[Doormatt]

Hey Everyone!

I've been trying to figure out if I should drill my new tank or not. It's a 37G, so I've been told it's more than likely not tempered. I figure I want to put two holes in the back, one in each top corner, and that way I can put a sump in the bottom of the stand.

However...I've seen a few posts (here and other places) where the people offering to drill claim that they're not responsable for cracks during or after drilling. This is the part that's got me worried. I'm not so much worried about a crack during drilling, that's life, and I can deal with that. It's the "after drilling" part that causes me to lose sleep. Has anyone had serious problems with this, or am I just trying to find something new to worry about?

Also, if anyone knows a place in the Surrey/Delta (or farther out) that drills tanks, it'd be most appreciated. (I've e-mailed OA, but they haven't got back to me yet).

Thanks again!
