Starting a decent model collection

Hi,

I want to start collecting good quality models of aircraft and am keen to buy my first model, a Herpa 1:400 Thai 747. I’ve only seen one company that does it:

Now it’s a rather pricey £25 plus a further £3 postage and packing, which is really expensive. Anyone know where else I might try to get it cheaper?

ebay is good, however, the British version has no models that I want, but the American one does. Even these people want about £7 or more to post it though.
