Seems about right on the score. Never tried the Monoprice but some of the other recent budget phones, the Xeport 5010, Thermaltake Isurus, and the Philips 3580. The CC51 and Xeport 5010 are about equal so a 7.7 score there. I said the Isurus could get an 8 or even more on the Joker scale though I don't subscribe to the AT driver thing(Isurus are a little older than the AT). Dsnuts saying the Philips are better then the Mono's and the Isurus are better still puts the scores right at those levels. ~$15 gets you near an 8 on the current scale. A year or so ago ~$15 got you an M9 or M6 on sale and you got 5.3 and 5.7.
Maybe there is a 9.5 phone out there for $20-$30. That is why some of still play on all the levels. It is fun and there is that holy grail out there somewhere:)
