I don't think posting the question about who to consign with is against the rules, only what you are planning to sell. Since both ****** and RDC are forum members as well as reputable, respected sellers, there isn't a right or wrong answer to that question.
You may make more money selling on auction but that can be a pain in this economy. And some buyers can make selling less than a pleasure and more of a headache. Consigning is less stressful but it does mean taking a bigger loss on the sale.
