The GW Thousand Sons Upgrade Kit is supposed to contain 31 pieces but the picture in the above link show 28 pieces plus the sorcerer. Does the kit have enough parts to convert all ten CSMs that come in a CSM kit? Or does it only have enough to convert 8 CSMs and the pieces to bring up the count to 31 are those of the included sorcerer?

Is it better to go to eBay and get one of the third party conversion kits?
