If you go to England or Switzerland (or know somebody there, or are willing to buy on ebay) get the Orange San Francisco aka. ZTE Blade
It's a very very nice phone for very cheap:
800x480 Screen
512 MB Ram
512 MB Rom
SD Card
Wi-Fi
3.2 MPix Cam
600 MHZ Processor
Decent Battery
Surprisingly good haptics
Tons of custom Roms
All that for the killer price of 99.99 GBP (~US$157) or even 119 CHF (~US$132) on prepay. It can be unlocked for free.
I already brought three of them for friends in Germany (and one for myself) - in terms of value for money, it's unbeatable.
