Currently, right hinged microwaves don't exist. Manufacturers would have to redesign and move all of the electrical components from the right to the left side of the oven and the cost to do this would be astronomical in terms of actual design costs redesigning the assembly line, etc.. Certainly, if the appliance community felt they would reap a profit on the investment, it would happen; however, at the present time, no manufacturers have jumped on board and produced such an animal.
Sorry I couldn't give you the answer you were looking for, but at least you won't be spinning your wheels looking for one! Let me know if I can help further.
Hello, Ikea offers a microwave that opens downward. http://marketplace.diynetwork.com/Product.aspx?Lid=2881-9120723&from=diy
