The range has changed somewhat, but I'm sure the principles are the same. I've got a 2008 Allez with 105 on it. I've done well over 10 000 miles on it and it's still going strong. I love it. It might not be as light and responsive as my all Addict but in its way I love it more. Supremely comfortable. I've changed the wheels and did have a bit of headset trouble (unique to the '08 model I believe). IMO it would be better than the Scott Speedster.
However, all my recommendations mean nothing if it doesn't fit you. Sit on one. Ride one. If it feels right, it probably is. That's how I chose my Allez.
