I really like fftoolbox and the ability to adjust scoring exactly like your league is setup. One drawback is they can be drastically different from ESPN, Yahoo, or other ADPs and rankings. Sometimes you can wait another pick to grab someone you like that ranks high on the fftoolbox list. Hard to get a feel for but easier online. Offline drafts can be tricky.
ETA: Good luck in your draft. I have one that starts in 30 minutes.
