Looking for a reasonably priced 20A power cord


I've decided to purchased a Niagara 5000 unit to power my system and I need a power cord for it, it doesn't come with one. The unit will be 20 inches from the wall socket so I don't need a long power cord. I'm looking for a reasonable 20A power cord, something of good quality. 

Any suggestions?

Sorry, I need to make corrections to my post.  For Audio Sensibility, the minimum 20A IEC power cord option is the Testament SE (not Statement).

That Voodoo Black Magic might be a good option because it's a huge 8awg cord which will carry a lot of current.  However, it's described as "micro-fine copper conductors", which tells me it uses very tiny strands of wire (not good in my opinion).  The Audio Sensibility cords all use OCC copper, which is better.

The nonoise suggestion of Cullen could be a good for the money option, but keep in mind that they use silver-plated copper and is only 4N copper (not a lot).

I just thought of another option here:

I suspect the VH Audio cables are likely the best of all the options we have discussed.  The "VH Audio flavor 4" cables appear to be what you want.  It's a large 9awg cord.  It uses "low strand count" bundles, which tell me the individual wire strands are rather thick (good thing).  I priced a 4 foot with Furutech Gold 15A male and a Furutech Gold 20A IEC for $408.  It might be more than what you want to spend, but I think it's the best option in this "reasonable" area (before pricing really gets crazy)
Well, I had decided to fork over the money for a 1m, Nordost Heimdall 2 with a 20A connector, and put the order in a couple of days ago, only to be told today by the dealer that Nordost won’t make that cable for me. Gee, thanks Nordost, my money is not green enough or I’m not spending enough, I guess.

I was hoping for a silver cable. Any other possibilities? My audio guru likes silver cable with gold contacts but I think that’s way above my price range.
Wire World Silver Electra 7.  It is a 12awg silver-clad copper power cord with silver clad copper plugs.  The Cable Company prices this at $490 for a 1M with a 20A IEC.

The Nordost Heimdall is only a 16 awg power cord.  Probably not the best thing you want to feed the Niagra 5000 power distribution unit (since this will be powering your entire system).  That's why I focused on larger awg cables (such as 8awg or 9awg).
Good point, auxinput.

My latest effort is to buy a custom cable from Cullen, this one:

which is 10awg and have Patrick Cullen install gold plated connectors on it for me. I’ve asked, I’ll see if he’ll do it.

Yes, this cable feeds the whole system, including the mighty Gryphon Colosseum stereo amp. I might upgrade the Gryphon’s power cable as well, It is currently a 12awg hospital grade cord.
