I have an older basic Foodsaver, bought at Costco about 12 years ago, still running strong. I've had to repair it a few times, the accessory that seals the top and extracts the air from the canisters developed a hairline crack and was leaking air, some epoxy fixed that about 5-6 years ago. I've had the unit apart a couple of times when it quit working, but each time, I found it was just clogged/dirty from meat juices etc, and that was stopping the thing from drawing a good vacuum. Cleaned it up and it worked just fine. Really simple inside, just some tubing, a motor/pump and some micro switches. What I've found is most of the time when it stops working, it's an air leak somewhere and is relatively easy to fix. I can probably keep it going until the motor/pump finally wears out, and even then I might be able to find a replacement for that. When buying bags on the FS site yesterday with the 50% off coupon someone posted,(thanks for that by the way) I saw a link to buy replacement parts but they only list gaskets and such...
