Its worth re-mentioning, that one Avengers LE machine sale, being sold under unusual circumstances doesnt mean all Avengers LE machines are worth $6400 at all, compared to the standard $8950 purchase price.  Relist the same machine over several different weeks on Ebay and get several different results, both low and high.

Just like if someone sold one for 12 grand, doesnt mean its worth 12 grand.

Best advice the guys have given is to play both machines.
