I recently watched seasons 1 and 2 myself. Which one did you think was better?
Also, if you're really anxious to get to season 3 you may want to try this link:

I was able to watch the first two episodes of season 3 with a couple of drawbacks:
- They take forever to download
- There are chinese subtitles at the bottom of the screen so you can't see what Jin is saying as the chinese subtitles cover the english subtitles.
But if you're desperate enough you can fight through it.
