A young fella (11 years old) came to the house to see my layout, he's into model trains and has a few hornby starter sets. Starter sets range between €80-150, which means he has to wait for birthdays/christmas before he can add to his own layout. I could tell he was frustrated, he can't fish for bargains on ebay the way we can. If basic wagons in blister packs were widely and cheaply available (€5-10), basic 0-4-0's €20, A bo-bo €30 - they could be bought with pocket money by young fellas on a weekly/monthly basis - which keeps the interest in the hobby going.
Hornby recently sold a continental lima shunter for £25 and a bo-bo for £30 and they sold out, which means there is a demand for cheap entry level products. The high fidelity stuff is amazing but without entry level stuff there will be no hobby in the future.
