Now that is just me, and my army building is 90% focused on the OT. I am sure there are some big PT fans that would love to be able to amass large clone armies.
My clone army is about 10x the size of my OT Army. I must have 500 clones in a crazy clone attack dioramma vs. maybe 200 imperials at attention for the Emperor's shuttle landing. For me, its been more about availability...when they make 2-3 new clones per wave and stack BPs full of them, you're almost forced to army build these guys....
That being said, I'd spend my entire savings on a battle pack consisting os SA versions of Biker Scout, Snow Trooper, Stormtrooper, DS Trooper, AT-AT Driver, TIE Pilot, Imp Officer, etc.
