IIRC the Coleman PerfectFlow stoves have a pressure regulator so the higher pressure tank should not be an issue.

As for cost, I haven't seen a dual burner Coleman PerfectFlow at $34 USD. That's ~1/2 the price of dual burners in that line and it looks fairly simple (that's a good thing).

Don't know for sure though, all I have here backpacking stoves from MSR and Optimus. I like the looks of this propane set-up for home use though (what I've seen online).
