I bought a chamber sealer maybe 8 years or so ago, best thing I ever did, bought 1000 each of 4 different size pouches for it. Ran out of the 8x12 ones and bought more of them, and need to soon order more plus some 10x13.
I went through several foodsavers over the years.
Down side to the chamber sealer is size limitation, although I never tried leaving something hang out side and seal it. I bought a vacmaster pro380 for a great deal got it and a couple rolls of 15" wide bag material for leas than half the cost of the machine, although it rarely gets used.
