I just bought a new Dell Inspiron 6400 here for roughly $1300 US, which is definitely more than it would go for in North America (can't say about the UK, though...). But seeing as it would cost just as much for me to hop a plane to a city where I could buy one cheaper than here, I can't complain.
I got it at a place called "The 220", at 38A Ly Nam De Street. Fixed prices (great -- I hate bargaining), the guy there spoke English... no problems!
They have the full range of Dells, Sonys, Toshibas, and I think Acers, too.
I had bought one Toshiba at BACH PHUONG's store. If you concern on Brand New, Hight Quality, Sealed, Original Systems Notebook, pls go to BACH PHUONG.They are trustable and reasonable notebook importer and distributor in Vietnam.
You can find them at www.bachphuong.com.vn.
BP's store at 120 Kim Nguu Str., Hanoi.
Good luck guy.
