Well Mike, being that it's the midwest and to someone that probably doesn't have a setup to grow indoors (lights, etc.), a Phal. is a safe and always, beautiful choice. The care is easy enough to keep up. I think Dends would struggle without knowing the scope of their requirements and what and when to recognize their overall changing conditions, in the negative or positive. Bulbophyllums grow well indoors but to someone who isn't necessarily into orchids, they can seem somewhat, unattractive, perhaps.
As for 'where' to buy from, there are so many nurseries all over, which you already know, I know
but if it's shipping you're looking to save on, then I'd suggest, ebay. Two vendors that I continuously buy from because their orchids are always in excellent condition are
terif1 and

Let us know what you decide.
