hehe... poor is not easier
There is a big difference between the EQ5PRO white and the HEQ5pro white.
I'm not sure the EQ5 could handle 11kg for photographic work. Most people think that around 11kg is the limit for the HEQ5 so I would think the eq5 would be more like 8kg.
Andrews have the HEQ5 for $1100, and the ED80 (OTA & dovetail only) for $599 at bintel... All up $1700, would that be pushing it if you sold some old stuff? ED80's often go for around $400 or less 2nd hand which would be $1500 bang on.
Or I have seen HEQ5's with goto sell for $700 or less on this site, then you could afford the ED100!
Its fun going over all the possibilities of new gear! One thing though, don't rush the decision.
