I've had the Foodsaver V2460 for a little over a year now (received for Christmas 2008) and it's been great so far, though the last time I had it out it was acting up some. I'm hoping that was a fluke. I'll know more tomorrow, because I'll be vacuum sealing a bunch of slice venison bacon.
As I said, the model I have has been great for me. I've frozen veggies, loads of pulled pork, venison bacon, venison summer sausage, raw steaks and chicken, etc. I also bought one of the marinading containers and have used that many times, though I can't really say for sure that speeds the flavorizing process up the way it says it does.
The Foodsaver brand bags and rolls are pretty expensive, but I've found that the Cabelas brand, a generic brand at Wal-Mart, and a brand that Sportsman's Warehouse carries are much cheaper and work just as well.
You definitely won't regret having a vacuum sealer. Let us know what you decide on and how it treats you.
