suggestion for service manual

So what is a good service manual for this car? I just bought one and would like an idea which one to get...
Chilton, Haynes? thanks.

Chilton's are usually a bit better than Haynes, basically the same, but I think I have found slightly more info in the Chilton manual.

I bought both of them. One give you some information that the other does not. I needed the belt dagram for my 2.3L DOHC and only found it in the Haynes manual. The Chilton has given me some info not found in the Haynes. You can never have to much info on your car.
