I just got some bags and rolls from Vacuum Sealers Unlimited. They arrived super fast are great quality and very cheap. Just Google that name. I found them from a different forum.I'm not sure what the rules are for linking to another forum, they offer a 10% discount code.
I can't comment on the specific model you referred. I do have a similar unit from target that works well. Food saver just had a promo of 30% off plus a 20% code attacked on top for bags. I almost did that but they place I got them from was still a little bit cheaper including shipping.
