Scott Leventhal's Pump Suggestions in no particular order :
www.silentaircompressor.com see Super Silent Pump DR-500; sale 4620 + S/H, reg. $ 900.
Thomas Industries Model 900-13-59E @ Granger Industral Supply
Wisa Rotary Pump & other aq. pumps starting @ $400 & up.
A note from Audio Asylum @ 1/3 HP Technmseh Refrige Pump
Scott also included some other links that were broken.
For my money the DR-500 is the one I intend to use, should the SQ go belly up.
