Ideal opamp means it doesn't have any parasitic behavior and it works as described in electronic books.I wasn't bashing LM358 by saying it's not ideal. I'd just use that...
I know you weren't bashing LM358 was just searching for alternative since I read that people have problems with LM358 even a guy who made this arduino shield wrote that he has some problems with LM358.
Thank you for your help.
Will feed you back when I get the components from China.
