Thank you, guys !
I ordered a bunch of rolls direct from Foodsaver. They would only match 1 for 1 for the buy one get one free deal so I placed two orders...
I actually bought the v3880 and used it already. I bought a 2# bag of scallops and seperated, bagged, vacuumed and sealed them. I bought 5# of frozen, tail on, uncooked shrimp but those didn't do so well. The tails kept poking a hole in the bag. I backed up and put the shrimp in a Ziploc frzr bag and tried it again in a FS bag and that worked. Last but not least I had several boxes of 5.56 laying around so I sealed those baby's up too. JIC.
