OK, here is the one I got from Sams here in the US :

Around $100 USD , but it's been a work horse for YEARS now so I consider it a solid investment. I can now shop around and wait for sales or good prices on meats I want to cook, buy in bulk and freeze them. I get pre-cut replacement bags on Amazon as I get annoyed trying to use the "roll of bag" myself, but your mileage may vary.
I use one both for meal prep and for long term freezing. If you want to really get the most out of meal prep with it also invest in a
sous vide. I can take a frozen pack of cooked brisket and a bag with a frozen lump of mashed potatoes, drop it in the sous vide at 165 or so and have a meal in an hour. No muss, no fuss, minimal clean up. If you want to go serious meal prep and freeze the meals this is the way.
It's what has let me enjoy cooking large briskets in my smoker. I smoke a large brisket, slice it, put 1.5 pounds into each bag, and vac freeze. I do the same with smoked pork chops. That way I do one big smoker run and have meats frozen and ready to heat and eat for a good while. Vacuum sealer + Sous vide will change how you approach cooking.
