It just depends what you buy. Sony has some excellent high end products, and some consumer junk that you can buy at walmart.
I purchased a Sony DSC-V1 about 4 years ago. The camera has about 8000 shots on it, and has traveled everywhere with me. Not a single issue.
I just had replace the original rechargeable battery pack last year.
The V1 is nowhere near professional grade, it is a consumer camera. Some of their new stuff that you see at walmart for $99, well YGWYPF..
The v1 was $499 new, I bought it open box and paid half that amount.
The only limiting thing about this camera is the amount of pixels. 5 megapixels is not much anymore. You can tell that my 8x10 prints are a little grainy.
My next will be a Panasonic Lumix. I'm just waiting for the prices to come down on those a little, they are in outer space.
