unavailability

I was wondering whether it is a good idea to get myself an ASUS laptop (N61Jq-X1) or an MSI (GE600) or Gateway(NV7901u) laptop from USA. Then I would be able to get Core i7 and ATi 5730 at just abt 53k. But, I am worried that I wont get any proper Service and Support because of unavailability...
