I found my PV500 Professional on EBAY being sold by a individual. Just be sure to verify their integrity as a seller on EBAY review the experiences other EBAY users have had with the seller and I always make it a point to reach out to the seller by contacting them regarding the item they have posted for sale. Even if they state facts that are important to my decision on whether to buy or not I ask similar questions again and ask for more descriptive details in regards to the the device condition, operation and why they decided to sell it. They pop up here and there you just got to watch for them or create A GOOGLE ALERT to notify you once a new listing has been posted. You will see alot of NEW UNITS but I saved over 300.00 on a like new system.
