Exactly. I am sure Accurascale could make a great model of a 20 but the current one on the market is being updated. It is similar to people suggesting the 60, there is not too much wrong with the existing model on the market (lighting functions could be upgraded). Suggestions should be commercially viable and not just wish-listing. There are other lower hanging fruit, e.g. Class 50 and many steam engines, that make more commercial sense and are much more likely to appear.
