Batel,
I used Manhattan GMAT perp books, and they were excellent. Manhattan knows how to balance between material drill down and plain tactics that work and help you succeed (I scored 680). I paid $178 for those books and now I'm selling. The books give online access to more drills – which I never used because the books had plenty – and to 6 adaptive examps, which were extremely useful).
Please let me know if you're interested and what's the price you wish to pay.
Good luck,
