a 7001DX from BigCeramicStore.com - DON'T!! Even at $54 with shipping, it was not such a bargain - or not yet. It worked for two test batches of glaze, and then turned itself off and will not turn back on. Aggravating! I've replaced the batteries with fresh twice - one set was brand new. No joy.
I've written to the support team at BigCeramicStore to see what they have to say about it.
