That wasn't an assumption. A dive shop told me that that's what I should budget for the overhaul. Remember, it's in Canadian dollars. Tack on 30+% as foreign exchange rate and "we have a very small market here so we have to charge everyone more for everything" tax. Oh, and 13% HST (our form of VAT).
I get it though, it might require shopping around for better prices.
Love to know from fellow Canucks what they're being charged for regulator overhaul. I understand there'll be regional differences so I'll keep that in mind as well.
