I have the V2840, and yes I would buy it again, however...
Costco has the latest model that stands on end, it takes up less room. Mine flips up on end, for storage, but I never store it. If you do, you will never use it. It must be left out, as you will use it everyday.
Another tip, I've heard folks say that they are out of bags and find them expensive to replace. Guess what, I reuse by bags over and over again. I wash in hot soapy water, rinse, fold and store in a large zip lock stored in the drawer with the plastic and foil wraps. My husband made me a dryer....he use a flat piece of smooth wood, drilled holes and glued dowls into the holes. I dry my Food Saver and Zip Lock bags over the dowls.
