As this has come back up... I would really discourage anyone not racing from getting an integrated aerobar like Wynrider has. They really are not the best idea for sustained riding, especially if you are not on a closed race course.

The thing is with a race style aerobar not only are the brakes out on the bullhorns (so no quick access to them), the bullhorns themselves are quite uncomfortable and pretty unstable to ride on, so if you find yourself in a situation where it really would be best to not be in the aerobars - traffic, steep twisty down hill, areas that require a lot of stop and go you don't have the regular bars/drops to fall back on.

If you don't intend to use the bike primarily for racing, I would really recommend clip on style bars to put on your regular handlebars. Then you always have the normal ones when you need them and you can remove them if necessary.
