Top rated readers have been a huge miss for me too - not just people who are expensive and have a ton of good feedback on Keen, but also those who get rave reviews on these message boards (QOC18, for example).
For me personally the readers I've connected with the most (and who have been accurate) are within the $5-$7 range who not too many people read with. I ended up stumbling up on them during a binge last year. If you can't seem to connect with top rated readers, I'd say go lower down on the totem pole. You might just find someone who works for you.
