We purchased a Vacmaster VP215 for fish camp and ended up getting rid of it in one season due to inconstant vacuum pressure on our fish. I called and talked with the manufacturer, who confirmed everything was working as expected, but regardless of all our efforts the thing just wasn't consistent enough for our uses.
What I'm not using at home is a Vacmaster Pro 380, it's a tank and hasn't had a single issue after a year of use. Our fish camp rig (that seals well over 500 packs of fish a season) is a Weston Pro 2300, it'll get a bit warm after 40-50 bags in a row and will need to cool off but other than that it's been running solid for 4 years without any issue.
For bags I've landed on these -
http://a.co/aU9jqHo There are cheaper options out there and thicker options for rough use, but these seem like a reasonable middle ground and they're super convenient with the rip top and built in ziploc strip. After multiple transfers between freezers and coolers at camp, then airport handling, then another couple freezer transfers at home, I'll get a couple failed bags out of 80-100 packages but not enough to really worry about. I haven't had any issues with bags packaged at home that go straight to the freezer losing their seal.
Foodsaver brand anything is way overpriced and underbuilt, we played that game for a few years before moving to Vacamster and Weston products exclusively.
