After a few years using my food saver and realizing how much I use it for huntin,fishing and buying in bulk. I’ve decided to upgrade to a chamber vacuum. I was steering towards the VP215 as there are many threads of people happy with theirs. I stumbled upon a youtube video and it looks like they added a vp220 and vp230 to their line 2ish years ago. The vp220 being a dry pump and the vp230 looking like the upgraded 215. Still oil pump but a bit of a bigger motor And 12” sealing bar. Now I’m wondering if i should buy the 215 or 230? Also what thickness of bags are people using? 3-4mil. I was going to buy a case of the max size and maybe some smaller thicker bags to try to freeze prawns in? i was looking at buying from webstaurant.com i know some have bought it from there. Do you remember how much shipping was or duty? Anything else I should look at ordering with it?
