Share 'Reasonable Chocolate Melters(Holding tanks like Mol'dArt) from England'

Hey fellow candy makers!I wanted to get a feel on how in demand are chocolate melters/holders, the kind that does not temper, but has a thermostat and keeps chocolate in same temperature.I used them in a chocolate academy when tempering chocolate.I have an access to them, and wanted to see if someone is interested in buying them in future near or far.Thanks.
