See the sponsors...
Di Bella / QCMS / Supreme Roasters etc
Plenty of other well known suppliers as well, but not going to give them a plug...
They will all do a range of grinders..
However $600 to $1200 is so far into the bottom of the range I doubt that they would have many / much of a choice... *Unless you go the one of the white goods suppliers for the cheep units.
All that being said.. *I am unaware of many up here, other than QCMS and maybe Supreme Roaster, that have service tecs on site or able to do call outs on demand.
Most of the suppliers up this way all shop out their service to a couple of service agents AND I have to say, that this does not always mean top quality service. *TAT can be an issue with items under warranty and the issues of RTB.
However; you could yet be pleasantly surprised.. BUT dont assume that if they have 20 machines on show, that they provide service directly..
