Get a Weston. Foodsaver quality cratered some time ago. They are not reliable. I have a Weston Pro 2300 that gets a lot of use and has been going strong for over 10 years. Before that, I had a "Pro" model Foodsaver that lasted only three years, followed by one that lasted only three months, followed by the last (a warranty replacement) that lasted all of three weeks.
After that, I asked my catering buddies what they used, and they pointed me to Weston. My homebrew supply store used them, too, for packaging hops, minerals, etc. I ponied up for mine and have had no cause for regret.
You will spend a lot more, as they run about $350, but that'll be the last one you ever buy. You do need to change the Teflon tape from time to time, and you'll need to change the heating wire every several years, but both costs are nominal.
