A pretty cheap brand of kitchen equipment in the UK is Andrew James. Their devices often have the appearance of "pro" equipment, while the build and price of normal domestic kit.
I've bought a vacuum sealer, electric slicer and ice-cream maker from this brand. All have been acceptable, and still work with no problems.
The AJ vacuum sealer is more fiddly than perhaps a better brand (it needs fairly precise placement of the bag edge and a very firm press down to lock), but I've been using it for a few years now with no problems.
