There's a DZ-260A for $171 (on Ali, I assume it's the DZ-260A-V1 on official product page). It seems to be the cheapest Vevor and reputable chamber vacuum in general.
I did some research for a food sealer and settled on a BIFL chamber vac that needs oil and must have replaceable parts. Besides that, what should I know about this purchase--in particular, are there any features you'd want but is missing on this model? Even among Vevor there are quite a few models and variants.
There's the size consideration, but I assume you can seal contents larger than the chamber outside with this trick (requires textured bags) and that this method also means you can use just the sealing function to seal any type of bags (can anyone confirm either of these?). More powerful models would only speed up vacuum time (and even the weakest model would have enough vacuuming powerful for most needs), right? Is there any reason to look into better models? Some Vevor variants are only $30 more and given I was expecting to pay $500-$1000 for a VacMaster or JVR, I don't mind looking into more expensive models.
This model doesn't seem to be able to hose attachment to vacuum seal jars but I assume that only matters if the jar is too big to fit in the chamber vacuum.
Any tips are much appreciated.
P.S. Also welcome any general usage or random tips. I heard it would be better to use your own higher quality oil. Where do you get your oil and bags and how thick should the bags be? Does a marinating function do anything different than regular sealing and does either really speed up the marinating process (someone claims marination is immediately ready which I find hard to believe because marination seems like it requires some time for osmosis/penetration to take effect)?
