Buyer's guide to telescopes at the best sites including Dome A, L2 and Shackleton Rim, both on the ground and in space, and telescope concepts to take advantage of their complementary scientific potential are discussed. A telescope at L2 requires only a little fuel to stay on orbit and can be accurately pointed despite solar torques by well established active methods based on star trackers, gyros and reaction wheels. Solar shielding on the Moon requires a polar location such as the high rim of the Shackleton crater, adjacent to the south pole, where there is also nearly continuous solar power. The disposable character of space telescopes to data is in contrast to ground telescopes, which are built as long-lived observatories.
