THE ruby on rails IDE for window's users

I've finally decided to move on from NotePad to a more Rails friendly solution. I got wind of RadRails last night in the rails irc channel (#rubyonrails) and boy am I glad I did. With the syntax highlighting and the code completion, I would say this could compete with the Mac's Textmate but since I've never used it, that's as far as I'll take that comparison. I could go on about my 3 hours experience with RadRails thus far but I'm not. So to summarize, RadRails == good stuff.
