Just saw this advertised this weekend. It's a small, hand-held gadget that sucks air out of specialty ziplock bags. Has anyone tried this? Anyone have a comparison to the Tilia FoodSaver? I've been toying with the idea of getting a FoodSaver, but have been balking at the high cost of it. If I can get similar results from a $10 appliance (vs. the FoodSaver $100+ price), I'd definitely be interested.
