Source for chinese vacuum sealers ?
 

Does anyone know a web address where I could have a look at or order
one of those rugged (heavy ?!) chinese vacuum sealers that they use in
tea stores across China to bag samples ? Those ones I have in mind look
more like makeshift rigs, no design housing and certainly not as sleek
looking as the stuff you can get in the west.

Any idea ?

TIA, Karsten
