Anyone have a vacuum sealer to use for things like sous vide cooking and fermentation? Looking at what's out there, the sky is very much the limit - I've seen professional grade machines upwards of £5k, but budgetary constraints mean I'm more interested in the £50 end of the market.
Question is, are the £50 machines any good? Or do I need to spend more to get something that won't fall apart in 5 minutes?
