The only downside to it was an over-preaching lead and not enough Mikoto. *shot*
Sorry, I don't know how good your Japanese is if you want raws, but Eclipse subbed them and Animetake also has links too.
So I guess I did it right then? ;D
May I recommend To Aru Majutsu no Index while I'm at it then? Railgun is its spin-off, so it has the same background and similar characters. Though personally I'd say Railgun has a better main protagonist and storyline.
Just want to say because of your enthusiasm for To Aru Kagaku no Railgun I decided to check it out myself and I'm already hook after watching the first episode of the anime. :D
