Best Ballast on the market ?????

I am about to drop some serious cash on some lights and was wondering what yall thought was the best out there? I am looking at 4 1000w Lumatek Digital ballasts with hydrofarm reflective hoods that have 6" holes for airflow. What would yall pick???? your dream setup if you will.............

ive been using the 600 watt ventronic sunmaster didgi and IMO is the best you can buy.
i would use the sunmaster bulbs as well for best results along with parabolic shades, i don't think they do 1000 watter's though..
