I actually have the VacMaster PRO350 at home and I use that a lot. It is a very nice machine, and it will last you a long time.
I also have a Weston Harvest Guard at home, and I actually prefer this one for small and simple jobs, like leftovers from dinner.
The Weston model is my choice for quick and easy vacuum sealing, and the VacMaster model for bigger jobs when I’m sealing a lot of bags.
If you do a sizeable amount of vacuum sealing though, I would at least consider a chambered vacuum sealer. The cost difference on bags is a big deal, plus they vacuum and seal much better. Non-chambered bags in an 8x12 can be $0.15 or more for each bag, while chambered bags in an 8x12 can be $0.05 or less, depending on how many you buy at once. If you used only 500 bags per year, that would make a difference of several hundred dollars in a few years.
The VacMaster VP215 is the best selling entry level chambered vacuum sealer. It is a real workhorse and definitely worth every penny. I have also become a big fan of the Weston Pro-2500. It is a couple hundred dollars cheaper than the VacMaster model, and if I were to buy a chambered vacuum sealer right now for me, I’d go with the Weston.
Overall, you won’t be disappointed by the PRO350 if you go that route. I would do an estimate on how many bags you might use a year though, and see if the increased cost of a chambered model would save you money in the long run by buying the cheaper but better chambered bags. If you have any specific questions on any model though, do let me know!
