I just went through the same thing, Had a hard time coming up with the
thermostatic sandwich adapter. Found one at www.coredcs.com/~wmeng ask for
Dick. I bought
a used 23 pass cooler locally for $45 and paid $77 incl shipping for the
adapter. Autotec in San Juan Capistrano, Ca is a source also but expensive.
Let me know where you decide to mount the cooler.
