John is looking for a lightweight grab-and-go outfit so I wouldnt be recommending an eq mount in any flavour.
I had my ed80 on an eq3 type mount and hated it. Im currently converting the eq into alt-az and ditching the counterweight
A big improvement in weight and usability.
As for the ED80 , I couldnt ask for any more for the price. If 80mm is enough for you its a keeper.
