I agree with rotuts, my 13-year-old edge sealer is not junk but still going strong and is good enough for all SV cooking, and sealing liquids is possible as well, see the links in my earlier post upthread.

I do most of my SV in zip lock bags and don't need a chamber sealer unless it would be more sturdy than the edge sealing units that don't hold up. I've had the vacuum sensors die and two pumps die with light use. Pedro, I'm glad you have a sealer that hasn't died. What make is it?
