Quite possibly a similar market to any business, ie. the one that reaps the biggest return. Place yourself in the position of the manufacturers, where all you hear are cries of woe mostly concerning inflated retail prices. So, what do you do - manufacture a lower quality, lower research cost, lower production cost, albeit slightly inferior product - however still make a healthy profit, because the market is telling you they want 'cheap' models...
...or, do you throw big money into research, development and high production costs, resulting in high cost stock with a potentially lower profit margin, and additionally the risk of stock left on the shelf because it is deemed 'overpriced' by the market.
Purely from a businessman's viewpoint I know which option I'd be pumping for. Okay, that doesn't help those, like myself, who prefer a highly-detailed and accurate model, however sadly it seems as though that is the minority market.
So I guess to those who wanted 'cheap' models, well... you got 'em this time folks!
