Generally speaking, folks looking at eBay at looking for a 'deal'. Based on selling prices on Audiogon, the $800 for a CDP-X707ES is not out-of-line (that said, my brother paid $200 for his from a kid in a high-end audio shop who turned up his nose at a "Sony"), with the -X777ES going for a similar number and SCD models for even more. Orion is not the bible. Just a guideline. And dual transformers, etc., are not the only things one is looking for in a CDP. Sound quality must be comparable to cost, IMHO. And the Sony's generally are regarded as the best in this aspect. But....it is your money and your ears. So get what sounds good to you.
