I have no experience with the Audiogon seller mentioned but have used Mogami 3103 for a few years now. Available online for under $3 a foot, I paid my dealer to terminate them with high copper content Vampire spades and also had them cryoed and burned in on the dealer's Nordost toaster. The 3103 is 11 AWG.
Seems to me my total cost was around $150 max including termination, cryo and burn-in for what is the equivalent of about a 12 ft. pair (I use unequal lengths).
The Mogami replaced, and bettered older (blue and black) Kimber 8TC, the current 8TC selling for around $20 ft. I believe. The 8TC had also been cryoed and burned in on the Nordost but was terminated with Kimber Postmaster spades which are pricey and probably not that great sonically.
The 3103 is a very good cable. I'd strongly recommend it if single wiring is adequate for you-if you require bi-wire 3104 is what you'd be looking at.
I also use a Jelco balanced tonearm cable, which is constructed with Mogami 2534 and it is a very high value cable as well; it replaced a DIY tonearm cable using Cardas wire and a Cardas phono DIN which was a fair bit more expensive than the Jelco.
