the Kodak EasyShare CX7530 is a really nice camera. 5MP and its really cheap. I got mine with a dock charger and rechargable batteries and a memory card at walmary for 175$. It is a high quality camera for home use!
I bet you it's identical to mine, only with a new case... I can't remember my model right off but the layout of the case is quite similar, and mine's 5MP and all.
Kodak makes ok cameras... I mean mine makes very nice pictures for the most part. My biggest complaints would be the lack of advanced/manual features, and it's speed(they are VERY slow)
The CX7530 is a lot like the DX7630 (predecessor), just a higher MP and a few other minor adjustments. As for the speed issue, you can always kick the MP down as you only need a 3MP size picture to a decent 8x10 (if you didn't know..., I think you do, but you never know... ). And over the last few years, that (response time) has been one of the features that camera companies in general seem to be improving, especially on the lower end. I have noticed that a lot in the cameras that have come out in the past 2 years with the new models replaced old/similar models.
