Over the last few months I have been considering trying an idea. I use a bread proofer similar to this one. It works really well to provide a stable temperature for dough proofing. But they are expensive to buy in small quantities. I was able to buy them from time to time at a price that made the effort worthwhile, but the prices have increased lately.
I have made contact with a supplier while is prepared to ship in quantities of around 10 that will make it possible for me to sell them under AU$80. (usually at least $95 - $110 online, plus delivery.) They no longer make these with Australian plugs so I will include an adapter in the price.
If you are interested, let me know, and I will see if I can put an order together. The price will not include paid delivery, but for Adelaide members I can usually make arrangements that avoid having to pay for delivery.
