optio330 vs optio330RS

Hi guys,

Does anyone know if there is difference in the quality of the lens between the 330 and the 330RS??

Everywhere I look on the net, the 330 is nearly double the price of the 330RS, despite it being the earlier model!

I have 2 friends, one has the 330 and one has the 330RS, and it seems that the 330 takes sharper pictures and has less interference from dust particles when the flash is used.

Please help. I'm thinking about getting the 330RS but now i'm hesitant. Thanks.
