I recommended you this small vacuum sealer on Amazon with bags and rolls. I have one and worked great for me more than 2 years now. Just have a deal on Slickdeal with great price:

The code is still work: T6U9XMCA. And they have $9 coupon too, so at last you can got them only for $25.39. Good Luck.
