Very Easy not a lot of knowledge required ,
i also had a spider9K but its very old and it would be a large upgrade for you i suspect ,
its a very good reliable box great tuner and fast blindscan
and easy input c/s info aswell as Biss/PowerVU/Tandberg and CCW Keys , with latest software patch already SRG 13E Pack is open and ready to watch aswell as few other channels without needing to add softcam keys etc which itself is very simple..
Very good for motorized setup it drives my 2 meter dish just fine ,
recording works fine to Any USB External Hard Drive
Youtube/Hardstation XXX and IPTV also fine with latest patch .
only 1 downside is like majority of all other boxes on the market right now no 4:2:2 support .
otherwise i'd rate it 9/10 for being very user friendly .
Hope that helps ?
Good luck : )
