IDE for RoR

Hi

I was looking for a good editor for RoR when I came accross with RubyMine. But I found it only to be a 30 day trial download. I know they are offering serial nos for free to opensource users but I currently do not have any projects to show them as I am learning RoR.

So can anyone suggest me an equally good IDE for RoR?

Any help will be appreciated.

Thanks
