Looking to get a vanda

[The Orchid Boy]

I really love vandas and I'd like to get one. I like ones like Ascda. Princess Mikasa 'Sapphire', V. Pachara Delight 'Sakate' FCC/JOGA, and V. Gordon Dillon 'Lea' AM/AOS. I really like the ones with big, full, round flowers that are blue or purple. I have a few questions...

Are there any that are easier to start out with that meet my description?

How do you grow them? Light, water, potting... I'm in Nebraska, zone 5a. I have all my orchids under T5s all year. Could the vandas grow under T5s all year or would it be good to put them outside? How should I pot them and how much water do they like?

I guess I should give a little more info about my conditions.
Humdidity: Cool mist humidifier running most of the time. RH around 60% to 75%.
Temperature: Day-75F-80F Night-65F-67F (Depends on how close the plants are to the lights)
Light: 4 foot, 4 tube T5 light

I am currently growing Paphiopedilums, phragmipediums, oncidiums, phalaenopsis, catasetums, masdevallias, and dendrobiums succesfully under my conditions. I'm growing nepenthes and phrags in what I think would be considered vanda light.

I'd love to grow vandas, even if outside part of the year. It would be pretty neat to have a vanda in a basket hanging on a tree or something. RH outside is usually never below 70%, summer temps range from 70F to 90F.
