Just went to House of Fraser in Birmingham UK and had a very brief play on the E80. The instrument isnt as heavy as it seems according to the specs. It doesnt have the same build quality of the G70.

For my purposes the inbuilt speakers really dont do the instrument justice. I have the PA1X and every arranger keyboard i have had has had built in speakers. Roland should have provided better. Got to dashh but will give some more feedback later
