I have had the Nesco one for several years. It is not one of the expensive brands and it has held up well for me. I bought it when they had it as one of their deals of the day. On Amazon it is always good to check their warehouse deals too.

I use my cold smoker to make large batches of smoked cheese. When I seal it in the bags it lasts a long time. I have some now that is 6 months old and is still good. I buy Alaskan salmon when it is in season and on sale and freeze individual portions so I can have it whenever I want. I have never had freezer burn with any meats that I have sealed.
It is not hard to make the individual size bags and saves money. The pre made ones can be wasteful.
