What is your strategy/criteria when acquiring orchids?

[dshallpost]

This is more of a general inquiry than a specific question, more on the "why" than the "how to."

As a newcomer I am interested in how you decide what to buy, where from and when. I have been acquiring some new orchids -- types I may be able to grow successfully now that I have some lights. But I am without a real strategy, so would love to hear your answers to the following -- and especially your rationale:

Do you focus on one type that you either (1) have the conditions for (2) simply like? Or do you have a broad array?

Do you acquire on any kind of regular basis, or when you find something you have been searching for, or when the mood strikes, or some other methodology?

Do you tend to buy in bloom, blooming size, young, or seedling? (I know that there was a survey done somewhere in here, but please tell your rationale)

Do you have multiples of the same exact variety, or one of everything?

Do you experiment, or have you found a growing regimen (temperature, light, humidity, etc) that works and that you don't tinker with?

Do you acquire from a wide array of sources, or do you stick with a few trusted vendors?

Any thoughts on these subjects would be appreciated!
