Looking for a good simulation draft site

Gentlemen... Greetings, and good luck on your fantasy drafts ...

I was told there are sites whereby you can plug in your league's specific scoring system and get projected season stats for players based on your league's parameters...

I was also told there are sites where you can have a mock draft against all computer opponents...

Anyone with good links to either of these formats, please chime in...

PS: I'm looking at Gore at 4 in a 12-team league...

there is a site called fantasyfootballcalculator.com where you can do a draft. It is against other people and it goes really fast. I thought it helped alot.
