i bought an Epson 4000 from the US, imported through amazon. Unfortunately there was something wrong with the bulb and i sent it back. The price of the projector was refunded fully, but i still ended up with the shipping costs both ways (i had used a forwarding service). Cost me around $500 without ending up with a projector.
I'm toying with the idea of importing the Epson 5040UB model (equivalant to the 9300, if I'm not mistaken), but I havent decided yet. There is a sizable price difference, but I might end up just getting the UK model and delaying surround speaker purchases. Undecided as of yet.
I'd recommend comparing the savings to the cost of returning an unwanted or defective item. Projectors are heavy items and it might make a difference to your decision.
