My dad has bought a CECT S688. Phone is quite nice, but the interface (layout) of the menus is a bit ugly. Also it works a bit weird. We can't load any MP3 or other music extension (which is supported). If we do that, the computer sees them at the phone card (micro-sd). The phone itself doesnt recognize them. Also if you're typing something and you want to go back you first have to clear (right button at the soil). Then the 'back' button appears... I kinda don't like this, or I'm just used to my Sony Ericsson

(which is almost death

)
Postive:
-Touchscreen
-Not the worst quality but also not the best
-Price (106 euro, 164 dollar)
-Big screen
-Only 1 port, USB, to charge your battery, transferring data etc.
Negative:
-The interface with the buttons
-Layout (my opinion)
-Warranty (not really a - point but if you've to send it back from Europe it'll take some time before you get it back)
-Touchscreen works sometimes not really, you've to press a bit, don't know if that's normal.... Our GPS device dont need that violation :P
Edit:
-No UMTS
I hope you've something about this information.
EDIT II:
Some screenshots about the layout (which I don't like)
