Phrag. Sorcerers Apprentice seems like a nice hybrid to me. It's not too difficult to grow and has many flowers in succession on a quite tall inflorescence. You just need some place for the huge plant.
An Update: I really like the long blooming period of this hybrid. There is always at least one open flower, a few days ago there were even three flowers opened, but when I took the plant to take a photo, the oldest flower dropped. So, anyway two flowers now:
