We have the Tilia brand FoodSaver and use it frequently. Our biggest use is packing meats when we bring them home from the store so they will last longer. We also will portion everything out so we only have to use what we want and freeze the rest.
I know Kohls has them on sale on-line. Besides checking epinions you can also search at mysimon.com for places that have them cheapest. Depending on what model you get they can get expensive. Another place I've seen them on occasion is Tuesday Morning.
