Yes I have a Vivitar 3.3 Megapixel with 3x optical zoom. It is not however the same model as was shown on that linked page. In fact I bought it about 2 years ago at Staples. I found out it was actually a rebadged Minolta model.
Overall I have been quite happy with it, takes nice pictures and haven't had any issues yet as far as reliability. I'm sorry I don't have the model # with me since I am at work and the camera is at home. Only thing I have done to it was get a 128 meg CF card for it since one picture in the highest resolution took approx. 16 megs of space. (the entire size of the card it came with!)
