Specific 2x8GB kit recommendations

I have 2x4GB of CAS8 DDR3-1600 now. I only have two slots, and want a 2x8GB kit. I'd like suggestions, one a low-budget (e.g. <$100) and one perhaps up to $130. I anticipate mild overclocking only, once I've replaced my stock cooler.
My two requirements are that it should be low-profile, and voltage for advertised timings (including XMP) must be 1.5V or less (which allows a little more for the overclocking).
