In the next couple of weeks I will be telling the story of weston pro 2300 vacuum sealer, and how it evolved from the v-33, cg-15 vacuum sealers. I might even publish the videos showing how I helped improve the cg-15 by pushing pragotrade to ditch the manual ajustment for altitude and go with a automatic pressure sensor. I'm sure you will find it very informative.
I will even show you some of the old videos that I made as I was beta testing the pro-2300 and the pro-5000chamber vacuum sealer we were working on back in January of 2007.
