I have the A300 and absolutely love it. Not an entry level by any means, but if you have the coin to drop on it then I say you cant go wrong.
I really wanted to get a canon, and when I compared the "feel" and what not side by side with the sony, I ended up with the sony.
the only thing I dont like about it is no movies....most dslr's dont do movies except the new nikon for like 1200 bucks.
so I just went out and got a digital video camera that records to SD cards that is actually smaller than my DSLR.
