These subjects are OK. I built the Italeri rebox of the Zvezda kit. Apart from some minor fit problems with the rear bulkhead, not too much else was required to make a decent T34. In all, an enjoyable build. I would imagine that the kits have probably gotten better over time, so a recent release might be better than the one that I built.
They come with vinyl tracks, so if you want to portray the tank over rough ground, you will have to do some surgery on the idler arms to get them in the right position, and then glue the track to the road wheels.
