Outdoor wok burners

[Anonymous Modernist 17003]

Anyone have experience with high BTU propane wok burners designed for outdoor use? I'd love to get some wok hai at home, and the idea of having outdoor stirfry gatherings in the summertime is quite appealing.. I looked around a bit and here are some models that caught my eye.

There are a bunch of cast iron 100,000BTU wok burners on eBay for around $100. Bare bones, but they look like they'd do the job. For $75 more, you can get a 100kBTU Thai burner that looks nicer and comes with a stand. ( http://importfood.com/thaigasburner.html ) . The most expensive burner's I've found have been from Auscrown / Rambo ( http://www.auscrown.com/page/shop/browse/a/category/e/highpressurewokburners ) but they look to be worth the price. I like piezo ignitions over pilot lights, especially for outdoor use. The HP200LPB looks especially hot (har har). Auscrown also makes a little stainless cart you can mount their burners in. Anyone using these or other work burners? Anyone know how they compare to similar out burners designed for turkey frying (or the stuff from Bayou Classic)?

And while we're talking wok burners, can anyone comment on induction wok cookers? My suspicion is that portable ones won't be able to draw the power required to get hot enough, but if you ran one at a higher voltage i bet it could get pretty scorching. But would it get hot enough to flame the breath of the wok?
