stand mixers

Does any one have a suggestion on which mixer I should buy.  I want something more powerful and stable than my Kitchen Aid.   I really like the features and look of the Electrolux, I see its a 600 watt and the viking is 1,000 watt.  Is one better than the other.  I bake bread several 2-4 x a week now.  2-4 loaves at a time.  Any feedback would be appreciated

Thanks, Erlinda
