I have the 1000HD combo and think it works great (but I haven't owned it for very long). Whether you go with one of Incra's combos for a sled or make your own, I don't think you can beat Incra's miter gauges. However, I don't see any great advantage to any miter gauge above the 1000HD model. Seems like that does even more than most people need. They are all extremely accurate once set up and squared.
