We've seen them occasionally at the following retailers, which are worth checking out. Kite Shop - First recommended by David Kline, this kite shop is definitely your best bet for a great boom in Austin. Carries a large selection of Colorado Boomerangs as well as the Aerobie Orbiter, some plastic Windsports tri-bladers, Fridolin Frost's ambidextrous indoor boom, and the ambidex foam Roomarang.
