This sounds like a pretty nice unit. I started out with a Foodsaver in 1988, it lasted about 2 years. I really punished it though, eventually purchased a couple of commercial units one from Bizerba, and the other from Koch Supplies. The first one was really expensive, 3k, the other I happen to be at the right place at the right time, 1200 plus four boxes of 4mil thick vac pouches. I change oil in them every year and they have been working beautifully for about 20 years and 5 years respectively. My kids liked to watch water boil at room temp inside the chambers while it pulled down the vacuum. If this unit can use the pouches that go inside the chamber, or doesn't need the channels like the foodsaver bags I can recommend a supplier that will ship a box of 500.
