I'm in Ontario, and haven't found normal BPs to be crazy expensive.
I got my guy, with a 36x18x15 tank, secure awesome lid, giant water bowl, and two pieces of baked hardwood driftwood for $310, about $350 after tax.

The snake himself was only $90, and from a good breeder within the province. Captive-bred, super tame, eating f/t. I am very happy with him. 8]
