I would also recommend a transcription of theBach Cello Suites. While rhythmically they don't have a lot of variety, they are an excellent source for becoming more familiar with recognizing pitches and intervals. (Of course I recommend picking up a recording to go with this).
I 2nd that...I have a copy of them, and they helped my reading emensly. I didnt dig the rhythm to it much. Mostly 1/16 notes, so its not that challanging as far as that goes. But its got lots of other stuff to confuse the daylights outta you.
Fourth, Standing in the Shadows of Motown provides some excellent chops-buster tunes. This book contains transcriptions to a number of Motown tunes that James Jamerson played on. They vary from basic to quite advanced.
I just got this book from the library today. You arent kidding IMO even some of the basic ones are hard. At least for me, because Im still having a bit of a problem with rhythmic values..dotted 1/4 notes and syncopation. So if you're new to site reading or not that experienced with it, they'll give you a good workout too.....thanks for turning me onto it azzho
