Oliso Pro-1000 Vacuum Sealer

A 20 count box of Oliso quart bags is $15 on Amazon. A 1000 count box of generic 6x8 vacuum pouches is $35. You don't need to bother reusing strip-style bags when they're that cheap. Additionally, reusing bags that have had raw meat stored in them should be avoided, if that's the use case. The counter space aspect is reasonable - the Oliso Pro-1000 occupies roughly half the space of the more compact strip-style sealers.

The Zip Lock vacuum bag pump will be fine for sous vide as you don't need the seal to hold for that long. You'll only start to see the effects of the inferior seal after several days. For food safety reasons, you probably won't want to reuse your bags, though. This makes using either of these systems relatively expensive. 20 quart bags will run you roughly $15 with the Olison system. That's pretty ridiculous, considering you can get a 1000ct box of regular vacuum pouches for $35.

Would you mind elaborating on the issues you have with the Zip Lock vacuum pump bag system? I just started sous vide cooking and was planning to use the zip lock vacuum bags to keep my costs down but still get the benefits of the vacuum. Would I be better off with ordinary zip lock bags or this system?
