I need some advice, I am looking for a good, non-scientific, calculator preferably freeware but I don't mind spending a few $'s but don't want to spend alot because it is only for ocassional use. I just need something that is better than the built in option. I have gone through Google and searched the site but mostly what I have found are scientific based so I would be grateful for recommendations/links.

Thanks
