Any keyboard that is two pieces and can easily tent/tilt upwards (like the Ergodox-EZ). You may get genetically lucky, but most of us run into tendon problems eventually. Keyboards that don't contort the angle of our wrists and rotation of our forearm can make life a lot more bearable. I use a Kinesis Freestyle for now, but will change to an Ergodox Infinity once I get around to building it. The 30 degree angle of the keyboard along with being able to spread the halves apart by 6 inches is what lets me type without pain. If I go on a trip with just a laptop, I can feel discomfort come back within a week. I also use a vertical mouse, the Evoluent. There are cheaper alternatives that are just as good.
