Has anyone used the Sony Ericsson K660i?

I really want to get a new phone, but I have to find a good deal if I want to get a really nice one. I saw a pretty good deal on the Sony Ericsson K660i, and I was wondering if anyone has used this phone. I want to learn a bit more about it, and find it helpful to read customer reviews. Does anyone know where I might be able to find reviews so I can figure out the pros and cons of this phone? Some phones have features that are really annoying, and I hate it when I only find out after I buy them.
