Keefer bros, talk to robert. I got a 32 jet mongolian for ~$110 delivered IIRC. If i were to buy another one i would get the 23 jet, 32 jet is awesome (15mins to get water to mash temp) but way overkill. Unless you're brewing in a 44 gallon drum you should get the 23 jet.
The mongolian kit comes with everything you need including reg.
