You might want to download Transmission 1.34 instead of 1.40 because there is some minor issues with torrents not downloading and saying "HTTP Status Code 0" (Link about the problem).
This problem seems to be isolated to version 1.40 so if you download 1.34 you should be good. Hopefully the "HTTP Status Code 0" error will be fixed in the next update (1.41).
I use Transmission too. I think Azeureus has one too but they changed name to something else I forgot. Tranmission is so simple and such a small program. Used to use Bitcomet for XP and that was crazier than this.
