Although this kit is of good quality and nicely detailed, its contents are exactly the same as the SU-102 Tank Destroyer kit #TSM9570, even including the 100mm D-10S gun tube. The SU-102 kit is even a tad cheaper in cost, even though it carries additionally both a metal and plastic version of that unit's 122mm D-25S gun tubes. Although I would recommend the kit to others for its good quality and nice detailing, I would also recommend the SU-102 kit in its stead just for the extra gun tubes that will be left over from a build.
