Its possible to collect the whole set so far on ebay at £19.99 + p&p each. wonder who buys past GBL issues at silly prices?
£9 for a single model to "play" with is a convincing proposition, its cheaper than buying moribund Triang/Hornby locos to cut&shut and experiment with livery changes and weathering effects. Anything more is madness. And if you want to collect the things, you'd have taken out a subscription,,,,,
