I have a foodsaver and it's good, probably could upgrade to make the process faster / easier.
A tip I picked up from one of Steven Rinella podcasts or shows was to vacuum seal approx. 1 lb packages of ground pretty thin and flat. Then u have a kind of "library" of ground and it can be evenly defrosted crazy fast just by placing in water bath. Makes it much easier to crank out a fast meal (tacos, etc) when u haven't planned ahead....really helpful when you've got young kids in the house like I do.
I own one. My uncle owns one. My mom went and got one. Buy it and you will be super, super happy. I've had mine for 6-8 years and use it quite a bit and it still runs like a champ. It does a great job.
I bought my Foodsaver at Sportsman Warehouse and it proved to be one of my better investments. I now buy meat and veggies in bulk and freeze them for a fraction of the price I have to pay for prepackaged stuff. I buy pork chops, chicken, and hamburger by huge family packs then break it down to individual servings for wife and I. Best investment so far.
Foodsavers are a money sink, IMO. They are designed to last x number of cycles and they they fail. I would get maybe one season of fishing out of one before they crapped out. The originals made in Germany, where bomb proof and repairable... the new Chinese will do one of 2 things. Stop pumping, or stop sealing. Some of the models have an auto shutoff to keep you from melting the sealing bar... Giant PITA when you have to stop and wait 5 min, and you have 200 bags of fish to seal. The seal bar is really thin, and if you pack wet items like fish, many of the bags will fail to seal properly. Their warranty is junk too. As a matter of fact, I bought a FS once for backup (got it on closeout at the end of the seasoN), didn't use it for a year, took it out of the package and it wouldn't even turn on. No returns, no refunds, nothing.
The cheap chamber vacs are nice, but if you're into production, the cycle time can be arduous. Pack up 200 bags, and you'll be into it 3+ hours. They also need to be maintained occasionally, and maintenance cab be a couple hundy. The bags are cheaper though, and they do liquids and fish very well. I do not think they preserve the meat/fish any better than a good vacuum sealer. The seal is all about the bag... use a cheap thin bag, get a cheap seal.
The best vacuum sealer I've found for the money is the Weston 2300 pro ($400ish). I can seal 2 bags (8" wide quart size) at a time. Its fast, and the sealing bar is 3/8" wide, vs 1/8" on the FS. I can cycle 2 bags in about 20 seconds, or roughly 4 bags a minute vs 1 bag with a chamber sealer... I've yet to have a bad seal. A FS vs. 100lbs of fish, I would have to redo about 5-6 bags, and I would find another another 3-4 in the freezer that let go. Sure there are workarounds with the foodsaver, like put a piece of paper towel in the bag to grab the juice, or freeze them slightly, but I don't don't like wasting time. I have zero bags fail to seal with the Weston, due to the larger sealing bar.
If you plan to use it a lot, spend the money. If you're doing a 100-200lbs of wild game, a FS will get you through a couple seasons.
