I have the G-Pen Elite, has a ceramic bowl, heat settings from 200 to 428°F by degree, etc, rated not too badly which is why I bought it.
When looking for such things, have a search on places like AliExpress because mine came from there, was the genuine article (otherwise I couldn't register it with Grenco) and the cost was a fraction of the RRP online, it was around €25 instead of €100+ from the more "official" sources.
Look around, you may get something considerably cheaper if you're willing to wait a little longer for delivery.
