Go for it. SE produce the most superb phones. I've had Nokias, Motorolas, Samsungs etc, but nothing beats SE in my opinion. Just changed from a V3 back to a SE. So pleased I did. I had the K700i before the V3 (urgh), and loved loved loved it.
I've now got a Z520i. Basic, but fab. I'm not into all the pictures and memory side of it, so it suits me fine.
