dosing pump selection help

[Amadod2]

Hey guys i just put together a 75g tank and need to select a system for dosing, i currently have a digital aquatics reef keeper light, so that could allow me to get individual dosing pumps, but i would have to get one more power bar for my reef keep at a cost of $100, my other choices would be either a vertex dosing system or a ghl profliux, what would you guys recommend and why??
