If you want quality, 6910R every time. It and the Breville are in different worlds; the guts of the Breville arent much different to the entry level Brevilles (except the Ikon which is a good buy), however the 6910R is a nice piece of kit and is capable of very good results! However if she only wants something red and doesnt care what it makes, the Breville will be a bit cheaper.
