I think you'd enjoy this camera as well. If I were looking, I'd have a close look at an A-700, but I really don't know what you're looking for in a camera. The A-100 may even be replaced soon by an updated version. I'm not sure about that, but it is getting older. If you waited a bit, you may be able to get it at a larger discount! I'd check Sony Alpha websites and read some of the rumours and news.
Just remember that there are 3rd party vendors like Sigma and Tamron that sell lenses for the Sony A-mount and Minolta's old mount. If you can't find what you're looking for from Sony, or if the Sony lens is too expensive for the performance and specs of that lens, then look for 3rd party options.
