I am looking for recommendations for a vacuum pump that I can use in the US and Europe. I found the CPS Model VP6D, for sale, but I cannot find any of the Yellow Jacket dual voltage vacuum pumps for sale. If you have any other recommendations please let me know. I would like to keep the price below $300.

I know this request for information may be in the grey area for this sites rules, since I am more of a hobbyist (also I home owner), and only service 2-5 car A/C systems per year for myself and friends. I was however trained on house HVAC systems by my father, and I maintain a cryogenic cooling unit (-50 C) for the USAF. So I am just a hobbyist, I just need a vacuum pump for my hobby of fixing cars.
