Hehe this question comes up a lot. Ive had a Breville 820 and sunbeam 6910 and Id go for the sunbeam over any Breville except the 900.
I used to say the same for the sunbeam grinder but now the Breville smart grinder trumps it. Stay away from the Breville BCG 450 (grinder).
You may or may not have luck getting the combo for $500 though.
