I don't have a FoodSaver but I really want one! My parents have had one for a few years and they love it.
I also recommend getting one at Costco if you can. They usually have the best price/bundle, but the main reason is their return policy if you either don't like it or have any problems with it. I'm not one of the (many) people who would return it after 3 years though if it broke...please don't do that.
I would only use a FoodSaver if you're planning on freezing items for longer than 1-2 months. If you are using up what you froze before that timeframe, it will be much cheaper to just use a freezer zip bag. The FoodSaver rolls are not cheap when you calculate how many "bags" you make out of a roll. They are better to use for more long-term storage or things that need to be airtight. So, using them to freeze 10lbs of chicken breasts would be a poor use of it. Freezing 50lbs (assuming you got an amazing price on the chicken) would make more sense, as well as freezing leftovers that you know you'll want to stock up and not use immediately within a few weeks.
