It's not so much a percentage that kills you, just a straight sales ceiling like with all the other merchants. Appraise only helps until you reach the ceiling (sales-wise, that is) and after that it doesn't matter.
He's actually not so bad in Chapter 1, but later, when the merchant redemption ceilings go up (7500, Ch2 and 10K in Ch3), he's no bargain anymore.
But once you've entered the Mimic's Nest, you are stuck with him, so you will need to bite the bullet if you need gold as we all do for those expensive True Names.
edit: BTW, I believe the djinni uses 25% instead of the standard 35% buy markdown.
