Hey, I'm looking for a decent vacuum sealer but am kind of clueless. Heres the reallllly tricky part, I need a super durable one. I'm planning on sealing about 2000 bags over the course of a few weeks. Cost is kind of a issue but my max is around 500 dollars. I don't need any fancy features, but I really need it to last until I can finish all the bags. I was looking at the vacmaster 260 pro, and maybe a few spare sealing strips. Any ideas how long a strip lasts? and what about doing it back to back with no breaks? Thanks for the help.
