This would be the next step up. With a 30psi regulator, it's made for cooking boiling 40 gallons at a time:
Amazon.com: Bayou Classic KAB6 Bayou Cooker with Hose Guard: Patio, Lawn & Garden
The SP10 sounds perfect, and after looking at the photo, that's EXACTLY what my brother used.............
He cooked with a Wok on this and at 185,000 Btu's...........Best Chinese food I ever had...........
AND FASSSSSST......
I'm going to order this today, at 20lbs, it will cost approx 90.00 to ship EPS.........LOL
