I don't know about the rest of you.
I have been using a home Vacuum Machine for 20+years now. FoodSavor sells them. I think Cabella's (mag) offers a model that is better quality than the best one FoodSavor puts out. I've worn out two - - - rather they quit working. I'd buy the best I could buy. STOP freezer burn......
It isn't cheap to do any of this stuff by the time you buy the equip. and supplies like different plastic roll sizes.
To me it is worth owning. Whether it be that duck, goose, deer meat, - - - I bought a half hog last week for 87 cents a pound.
Compare that to $1.79 a pound for that pork roast.
I'm always using my Vacuum Machine to preserve foods. It extends Freezer time by months without freezer burn. Reuse those plastic bags too.

When it comes to Marinating anything, oh yes, only way to go. DEEP PIT BARBECUING, I dump in all the veggies, meats, liquids and so on and seal it. Big long bag. Cook everything righ in the bag. A-Huh, much better and no mess.
