Definitely consider a Shunyata Venom HC power cord. 20 amp IEC plug termination seems to be all that's available now. $175 for 6 feet new from Music Direct or The Cable Co. Well worth it though you'll need a 20 amp cable to 15 amp IEC converter. Of course you can spend plenty more on a converter from Shunyata or Voodoo Cable ($75) but after break in, I heard little difference between a $10 generic and the $75 Voodoo Converter (the latter bought used for less, fortunately).
Note as well several recommendations of the Analysis Plus Pro Power Oval made in various threads by one, Geoff Kait. 6 foot length/15 amp IEC termination available new for ~$110 right now from Musician's Friend and Guitar Center.
Good luck in your hunt.
