I have not heard of Mainstreet .. but there is a "Mainbrew" in Hillsboro. Used to be downtown, now just off of US 26, on the North side. That is the only LHBS I shop at and have done so extensively. Know, like and trust the people there and products. I did, however, buy a kettle online and went to talk to the owner of that LHBS and he said they were carrying the same product as I ordered, but the shipment had not gotten there yet. They have two grades in the generic kettles, a thin SS and a thicker SS. I got the thicker one and am very happy. Thick and heavy, but strong sturdy handles and nice thick bottom with even heat distribution. They also carry the Blichmann products, and their inventory seems to keep expanding on the Blichman products. Neighbor across the street has an all Blichmann all grain setup and stand and it is good stuff. But NG does burn different than Propane and you need to change the nozzles. Also, I forget which way it goes, but I believe NG burns hotter and not quite as clean as propane (or the exact opposite), anyways 1 will take slightly longer to heat.
