It works great in my opinion for a cheap and cheer full groupset. Easy to set up and maintain, and will work just like any other Shimano group.
Only down side is that you cant change down a gear if you are in the drops because the shifter is the thumb shifter on the inside of the lever. Having said that its the same as campag, so it might not be a problem, for you.
I would say go for it, alot better price than anything else. I would be tempted to wait for the new SRAM Apex group, but thats not going to be anything like the sora price..
Hope that helps
Cheers
