I also have the VacMaster 112. Does a great job with liquids, I've made stock quite a few times this month and appreciate its curved chamber. Don't forget to chill your liquids, we had a nice boilover inside the vacuum chamber when we took stock from the pot directly.
The bags for the edge sealers are about 10x more expensive (50 cents vs 5 cents) as they require a matrix of ridges to suck air out.
