Best Bang for the $$$ AC Power Connectors?

Thanks Guys. Much appreciated. One question I have is concerning the unplated copper. How often do you need to clean the connections? I've heard good things about the Furutech F1-11 cu. My problem is that I'm a slob when it comes to cleaning connectors. I always forget

I only unplug my system once a year for a family camping trip and then clean it with copper cleaner when I return.

My favorite connectors so far are the Oyaide Armored series - AC-004/AP-004.  The only real downside is that they're only available in Japan, so need to order them through eBay.  The 004 series have the same plating as the M1/F1, in a much less expensive package. 

IeGO aren't bad either, but are pricey for what they are.  I much prefer these to Furutech.  

I too love Furutech's products. Recently I purchased a used Kimber Kable PT 14 Ascent PC @ 2m, cut it in half & used the Wattgate Evolution plugs that the cable was built with. These things are built like a tank! I especially like the Allen key socket, held like a charm.

wattgate WG 330 AU evo (gold) or Furutech base unplated copper. 
Use high quality outlets as well. 
I clean connectors once or twice a year with deoxit. Takes minutes. Set a reminder on your phone.
