I've got a Nikon D60 and love it. I bought the kit, but also have an additional 55-200mm VR lens which is pretty versatile. The kit will include an 18-55mm which is good for general everyday use. I have absolutely no complaints about it at all.
I've also got a Canon IS1100 that I use as my standard point and shoot. It does it's job quite well.
Personally, I didn't care for the viewfinder on the Canon DSLR's, so I went with the Nikon. Prior to that, every other camera I have owned had been a Canon.
You'll want to get something that can use a wide variety of lenses from various manufacturers. I highly recommend
www.dpreview.com for various reviews.
Also, it may be very important that you get a camera that supports non-auto focus lenses. There are quite a few lower end DSLR's that don't have a mechanical focus drive pin on the lens mount. This means you'll have to buy a lens that has the AF motors inside of it, which can get pricey.
Edit: One more thing. You don't see too many "pros" carrying around Sony cameras. Nearly everyone uses a Canon or Nikon. There's a reason why, aside from the fact that Sony is fairly new to the DSLR market.
You may want to strongly consider the Nikon D40 or D40X. Great "entry" level DSLR's that support a ton of lenses. When you get more in to this in the long run, you'll be replacing the body anyway and buying lenses that cost more than most bodies do. It's very easy to find lenses that top several grand.
