I've been thinking about getting the top tier as well. Have a b-day coming up and will use any gift cards to help with the purchase. my current setup, which really isn't a set up at all, is getting old. i've seen several posts on other forums where people bash the stand. well, i'm not a welder or builder and this will suit me just fine. i saw it in action at nhc 2010 and talked to John Blichmann about it several times. Let me know how it works out and how the pipe setup for the mulitple burners goes.
OK, got my Top Tier system Friday, and it's a good thing my father bought me an erector set back in the 60's, as there is much assembly required on this thing. Got it all together (minus the gas manifold) before going to bed Friday (My black IPA was catching up to me)
Saturday morning, went to Home Depot, go two lengths of 24" gas pipe, and had it completed by about 10am. then life happened. Sunday morning we through a "dry" run with just water going from pot to pot, checking boiling times, etc. Basically, just getting used to how it all works before I through some grain in.
I give it an A+ so far. Gonna brew my "chunky dunk" on Sunday.
