My first mobile phone Motorola CD928+ was purchased at 2000, it took me about US$260
Second mobile phone Ericsson A3618 was purchased at 2002, I only spent about US$10
Then I just bought my third mobile phone last month, Moto V180, price is about US$90.
If money isn't an issue, I might consider to go for:
Moto V600i, E680, E398, or
Dopod 575, 818
As for Dopod 818, it's boundled with MS Win 2003 for SmartPhone, and build-in with 130 mega-pixel CMOS digi-camera. Recent price is about only US$590....well, too expansive for me
