@justashopper - I love my FoodSaver (it's the "GameSaver" version, which I believe has the broadest range of features from this brand) and have had it for many years. Even though I don't use it all the time, when I need it, I'm very happy to have it. Just this week, I portioned and froze a batch of Heartland Fresh chicken breasts and some soft pretzel nuggets from The Pretzel Co. that I bought here at QVC. And tonight for dinner, I'll actually be opening a package of frozen Authentic Gourmet mini croissants that I bought a couple of years ago and "Food Saved" for later. 
Although I primarily use my big Food Saver for long-term storage, I also have a smaller handheld version that works with specialized bags for shorter-term refrigerator storage; it gets used frequently for cheese slices, deli meat, and baked goods.
If you get a FoodSaver, there's no need to spend extra to get the same brand of bags, though they do often go on sale both locally and online for good prices at times. For the past five or six years, I've been buying the OutOfAir brand bags on Amazon—they are very high quality and come in a variety of sizes (I most often use the quart size).
One final note: I have found that the bags always seal and retain freshness better than any of the container options that are offered, whether from FoodSaver or another brand I tried (don't recall the name).
Good luck!
ETA: I just searched the QVC website and found that they have a FoodSaver model with some great features, including an accessory port if you want to try using the containers and the bags: https://www.qvc.com/foodsaver-vacuum-sealer-machine-system.product.K91586.html?sc=SRCH
(There is also a really big FoodSaver set that includes containers, bags, and even a handheld sealer; some of the button commands seem odd, but I just don't know what they do, so perhaps this big deluxe version would interest you:
