Your opinion on FoodSaver by Tilia?

I am generally not impressed by products sold via TV infomercial, and usually have a certain amount of fun picking out the scams and tricks used, such as the chemistry tricks used in the old "di-di 7" spots and the current Oreck vacuum commercials.

However, I was intrigued by the FoodSaver by Tilia commercial. This is a kitchen appliance--much like the old plastic bag heat-sealers that came about in the late 1970s, but this one (marketed since 1998, I think) has a vacuum pump so as to vac-seal foods in special plastic bags and mason jars.

I am wondering if you have used this product long enough to have a good evaluation of it.

Are the additional supplies affordable, or do they sell the appliance at a reasonable price, then screw you with the needed supplies?

Thanks for your thorough reply.
