The Nemox and the Lelit are the same machine branded under different names. Have also been sold as the Quaha Napoletana II (as well as other names). All are made in the same factory in Italy.
For your budget I would highly recommend this machine. Unfortunately I dont think theres anyone in Adelaide who sells it. I have a Napoletana which is now 5-6 years old but still going strong which youre welcome to play with.
