I bought a time machine September 2008. It broke down next week.
So I took it back to the shop, the shopkeeper said, "they don't make them like they will".

I think it's mainly because TARDIS' are grown, not made.
They cost a little more, but they're worth it (you get what you pay for).
Make sure it's a real one and not a knock off though!
It should have the Gallifrey watermark on it if it's the real deal:
