I'm afraid that I am not up to speed on Canadian suppliers. I suggest that you start exploring the ECF
Canada Suppliers forum – for this and/or other purchases. Unfortunately, "vgo" doesn't come up on a search in that forum. "riva" does, however, at
Electro Vapors. Actually, I don't think their "eV UNC Riva" is the EastMall Riva. Whoever the manufacturer is, it has a 1300 mAh battery.
The U.S. supplier, with which I'm most familiar, who carries the VGO (and the Riva) is
BreezEsmokes. In fact, Don
only carries fat batts. [I don't know whether he ships to Canada or what the cost would be.]
His full two-battery/one-atomizer VGO-900 kit is $46. He also carries a one-battery "Sampler Kit" for $26. I think I'd go with his $48 Riva 1100 ($2 more for 200 more mAh, an extra atomizer, and a line of models with more of a track record than the VGO). [In fact, since I am a penstyle man, I went with the Leo (from
Vapin' in the Cape, but BreezEsmokes is an excellent supplier as well).]
However, BreezEsmoke's $40 KGO-1100 comes closest to matching your requirement of "just cheap 510 with a big batt." I've heard of the KGO, but know nothing about it. It could be a fantastic PV ... or not.
Of course, if 750 mAh is sufficient, that $30 deal (using "ecf" discount code) on the Riva-510 "LITE BUNDLE" from
Liberty-Flights can't be beat.
