The Oscar is, indeed, a HX machine, but I do not believe that it is an e61, nor, IIRC, does it use a thermosyphon. Isn't the HX accomplished by a mass in direct contact with the boiler? In that regard, the Bezerra BZ02 is also a non-imposing, non-E61 HX machine, with the additional feature of a hot water tap, which the Oscar lacks, and, perhaps, better prospects for the internal electronics holding up over time.
