I am a proud owner of Motorola C650. I bought it for Rs 5,300 (First hand) I find the menu interface is easier than the mobile phones with "Symbian OS". The pictures quality is reasonable at a resolution of 640 x 480 pixels. I am not advertising my home page, but you can see some pictures taken from my mobile at h..p://www.geocities.com/tumkurcity/
Just make sure.....
.....it comes with a Data Cable and Motorola Mobile Phone tools software
.....All the features mentioned on some of the reviews site are fully functional.
Do post the flex version of the mobile handset.
Settings > Phone Status > Other Information > Flex version
Otherwise, The price quoted seems to be ok.
