David Rush (retired college professor, and playwright with resident and off-Broadway credits) has a new-ish adaptation published by Playscripts, Inc. I stress "adaptation," as it's not just a translation of Sophocles, and at times it diverges from the source, but it captures some of the majesty and power of ancient Greek theatre in terms that modern high-schoolers can understand. It has the added advantage of playing about 75-80 minutes, which saved me the trouble of cutting a full-length translation, when I knew that we were going to give some performances as assemblies during our 90-minute class periods.
