@Troubled...not using anything larger than 5gallon. And actually interested in an electric vacuum so I can avoid heavy lifting. I need to order an auto-siphon so it easier to start the gravity racking, until I find the ideal vacuum. Thinking of an electric vacuum pump, no-oil, 1.5-2CFM (hope I got that right), with a gauge and control. Watching eBay and Craigslist for HVAC units and checking under "aspirator", "suction device", "portable suction", "electric vacuum". Just not familiar with brands beyond medical equipment such as GOMCA and Invacare. Could kick myself in behind because Amazon had new 1.5CFM electric vacuum with gauge/control for $57 free shipping & I was just beginning my research and did not know if that was the right thing. Turns out it is, and of course it is not available at that price any longer. Alas, I will find one!!!! But, I am always open to suggestions of others. Thanks.
