A 3 to 9 scope is all you need.
Ditto for a .30/06.
You might be able to locate a used Winchester 70 Featherweight in '06 with a VX-III or a Zeiss Conquest on it that is within your budget range. All the better if the current owner will let you shoot a few groups out of it before you seal the deal.
That combo with Federal's new Copper bullet or the Vortex loaded TTSX in 165 or 180 grain weights and you are GTG on your safari.
