We now have 11 studios with another 2 opening in 2 weeks. 4 in OZ after Christmas , so wont take long before i get to you.
The Korean versions wont work well for you. The low KG rating is an indication of it being underpowered . The problem is they where designed for Physio work only by Smitechasia , a medical company . Brillant for Physio work , but not really made for a workout. I buy other equipment off them , but not those. Sorry you will just have to hold on.
By the way, i have my own model out now. 3 times larger with more you can do.
