LOL, I had been watching that auction myself...
Fortunately, I found something a little more compact to suit my needs:
Lytron 4120
I'll take some better pics later, (I just received it today) that pic is from the auction. This came with 2 120mm AC fans (Nidec Alpha V's) and has 3/8" ID connections. Stainless steel tubing and copper fins. Brand new, $54 shipped ($352 retail).
BTW, if you need a Comair Rotron Caravel to slap on that thing (that's the fan they designed the mounts for), I have one for sale.
