The market place is driven by the same thing regardless of if it's a VH or AAH and that is CONDIOION. I cruise the web and see DH/DHE 20's from $5K-10K. There is a well known dealer with a BHE 20 for $30K and it's been on his web site for a while which considering the rareity of a straight stocked BHE 20 is surprising. I have seen a GHE 20 with an asking price of $20K in very high condition.
Just goes to show you there is something for everyone. I just wish I had a spare $30K
