Andy, welcome to the Alpha club.

My SWMBO and I are both former Minolta SLR users (we literally wore them out). When we heard that Sony bought out Minolta it was only logical to examine their products as a replacement for our old cameras. I bought her an Alpha 100 about three years ago and we splurged on an 18-200 Zeis lens. We have never looked back and she got me my own A-330 for Christmas so I wouldn't be always messing up HER camera when shooting models.

BTW, she just took a college photo course that was super intense and she and her Alpha came through it with flying colours. She started the course with 3800 pictures having been taken on it. By the time it was finished the camera registered over 8300 pictures and still going strong.
Cheers,
Jan
