Viewing a Soyuz launch on the cheap?

So in 2010 I was in Florida at the scheduled launch of Discovery, only to have it delayed until February of 2011 :( Alas, I was not able to return and therefore will never get to see a Space Shuttle launch.

However, since travelling through Kazakhstan last year, I've become more aware of the 'Russian option' of Baikonur and its Soyuz launches. However, the only info I can find is that to view it is expensive. And that there may be a rather large exclusion zone.

Is there a cheapish way to get to see one of these launches, assuming you're already in Kazakhstan? And by cheap, I mean backpacker-cheap ;)
