I too am a fan of the Weston Pro-2300. I had two foodsavers that lasted less than a year each, and they do not repair them or sell parts.
After that I decided i needed something built a little better with user serviceable parts available. I am going on 3 years with the Weston and have had no problems. A perfect seal every time even with liquid between the sealing bars.
Be forewarned, this is not a unit you can tuck away in a cabinet until you need it.. It weighs about 40 pounds and has a large foot print. We have a second mini-kitchen we built in the basement for BBQ, canning, and other food prep. It is a permanent fixture there and we vac-seal 10-20 bags per week. Best money I ever spent for freezing food... I found items that got lost in the freezers for over 2 years, I thought they would be bad after all that time, after opening them there were no signs of freezer burn and when cooked for a lunch to test them, they were just as fresh as when they were sealed.
Keep in mind that whatever model you decide to go with, unless you have a chamber sealer they do not like liquids. There are way around this like chilling the contents before sealing to thicken the chili, soup, broths...
Good luck on your purchase.
