I wish we could afford that right now.
i know this is an issue BUT you will buy one later and wish you had gotten one sooner so the unit will end up costing you more in the long run. its a worthwhile investment. hell i will just send you my food saver to use until you get enough to get a good unit.
Do you have the Weston pro stainless model?
Here is a good place to order sealer bags. I use them all the time work great and are cheaper than food saver brand.
