I just bought the FoodSaver 3880 at Costco for about $150 plus a box of extra bags for about $35. I’ve used it on about a dozen items including 5-pound bags of flour and bags of seeds, etc. and I’ve been pleased with the performance. Of course, time will tell if they stay tight. I put them in large tin “lard” cans which I’ve been getting from Lehman’s out of Ohio.
There is also an attachment for the FoodSaver (on Amazon) to suck the air (or some % of it) out of standard wide-mouth canning jars. I haven’t used that yet.
