I am building a HERMS system with 3 other guys and I have bought quite a bit of stuff that I will not end up using. Some of it is brand new and the other stuff has only been used in 1 single brew. There are some great deals here if you are trying to go the converted cooler route:
1 10 Gallon Orange Rubbermaid Round Cooler, no modifications, used 1 time as Mash Tun, some warping of the inside due to heat, but should still work fine. - $25 (Normally $50)
1 10 Gallon Orange Rubbermaid Round Cooler modified as Hot Liquor Tank. Has 1500 Watt heating element installed using an o ring and copper fitting as a nut. Has two holes drilled in lid. I can send pictures if you are interested. - $65 (Normally $50 for cooler + $50 or more for all heating element parts)
1 12" Phil's Phalse Bottom - Brand New, Never Used - $20 (Normally $32)
1 10 Phil's Sparger - Brand New, Never Used - $15 (Normally $26)
1 12" Stainless Steel False Bottom, Used 1 Time: $25 (Normally $30)
1 Stainless Steel Sparge Arm, Used 1 Time (missing one end cap, replaced with small cork) - $25 (Normally $38)
If you buy individually, that is $200 for everything. If you will buy it all at once, I sell it for $165 (free Phil's Phalse Bottom and Sparger).
I am willing to ship everything besides the rubbermaid coolers.
