Hi Dennis; welcome to the board. $1,550 is not an unreasonable price for a 5 string Essence in good condition. I think it is the case that most Alembic buyers probably prefer a natural finish rather than the red finish; so I'm guessing that may have an effect on the bidding for the bass on Ebay. Also, the knobs on the Ebay bass are not Alembic knobs, which affects the value a little. And the Ebay bass does not have a case, which also affects the value. Personally, between these two basses, I prefer Mike's; primarily because my personal preference is for a natural finish and because I prefer the Alembic knobs. But that's just my personal preference.
