Tim,
These large spotted Phals. are quite popular at the orchid shows with the public. Carmela Orchids in Hawaii has them and will ship as a reputable firm. Norman's Orchids also sells them. They have been available at many of the orchid shows from other vendors this year and pop up from time to time at the box stores like Trader Joe's, Cost Co. and Hope Depot. There are many different crosses with the markings you like. Some stem from the Phal. Brother hybridizing. You should not have to pay an "arm and a leg" for one so buy smart!
