Try to get one from a good brand- at least that way you may not get all the latest features like 2MP camera, but you get a nice interface which is solid.
I think Samsung D500 might be in that price range if you buy it from like one of those shops in Market City or Capitol Square whereby they don't have so many overheads for a nice store kindof thing; if not, the above recommendation for the Nokia is pretty good. Feature wise it's not that strong, but the interface is solid (especially their flawless T9 implementation for SMS'ing) and after using many phones over the years (SE, E, N, Samsung, P, M, Siemens, Sagem) I've come to appreciate a solid user interface.
To Nokia 6111's advantage over Samsung in this case is slightly more solid UI and Bluetooth; and it's also a new phone. However, Samsung's award-winning D500 is also a solid choice with it's nice interface (have to admit Samsung has improved alot over the years) and it's got slightly more appeal because it has "pretty ringtones" (in comparison to Nokia). Mind you I haven't heard all the ringtones on a 6111, but Nokia's ringtones tend to sound bland in comparison to Samsung.
