Where to Practice Verbal Section other Than ETS Official Guides?

GRE Verbal Problem Solving
1

I know that Greg has suggested using Manhattan 5lb Book for practicing quant. However, I do not want to complete all the verbal questions on the ETS official guides in the initial stages of my preparation. I am looking for a reliable resource to practice reading comprehension questions with long passages, but there is nothing for it like there is Manhattan 5lb Book for quant.

Do the official ETS guides have hundreds of reading comprehension questions with long passages, or is there is a resource from where I can practice as much as I want?

Big Book?

I have felt that the passages on the Big Book are relatively easier than those in the official guides. Are you sure they will help in preparing well for the real test now? What I know is that Big Book used to be for the old GRE.
