Thanks everyone for your nice comments. The Dendrobium is one of the newer, more compact ones, supposedly easier to grow, and blooms often. Still gets gangly though! I've never tried a standard Nobile.
Swamper, the Green Hornet is very easy to grow and seems to always have a spike somewhere. You'll enjoy yours.
Sandy, I love the Miltonia flowers but find the plant (at least mine) kind of untidy looking, and very susceptible to mealybug. I just keep working away at it!
