I seem to remember that most of the cabinets I seen were professional, ie. barrel locks, sliding doors like shop fittings.
I agree with you that 1:43 is a tough scale and Ebbro is certainly not the best, I've seen Ferrari models that look like they were hand made but they were $250 plus!
Ebbro is less than $100, made in China but still very good, I see no paint flaws unlike other models and I find plastics to be good although I cleaned some flashing off them.
Well this is more for Denham's benefit...
1. Forget R32 Ebbro. They all stopped production long ago.
2. R33 Ebbro might be available but still rare.
3. Some dribbs and drabs of the 34 still available.
I got mine various model stores but mostly from an SAU sister site:

Andrew will help you, he's been good to me.
I am still after an R34 Mines tune and perhaps a Nismo tune model.
I suggest that perhaps this is the right one for you:
