So far...I'm not complaing
When I've stopped making kit in 1990 there were few kits and they often were JUST CRAP. The best kits were produced just by Tamyia (or Hasegawa if you did aircraft kits) Internet had a low widespread so it was very difficult (and expensive) to find good photos or drawings. Extra sets were few or difficult to find (pratically just Verlinden and Eduard made extra sets in that period. The small shops usually didn't sold our products....and you couldn't order it on line....) To made a good model, you had to do a lot of scratch works...sometimes it was funny....sometimes it was BORING
Now, we are a lot luckier. The high level kit companies are more than the past and every mouth made a new stunning kit. That' the reason why the subjects are often rare or unusual. Pratically now there' s an extra set (resin or Pe) for every kit on production, and we can find easily photos or drawings which depict the tanks that we have on our workbench
So, in my opinion, for a decent T72 (or T34 exagonal turret) kit....we have just to wait patiently...don't worry
