Locating Oncidium onustum/Zelenkoa onusta?

[JonnyBravo]

So I've been away from orchids for a while, just keeping my few very favorites as I've moved around a lot and devoted my time to my family's new cafe. But things are finally smoothing out, and I've got more free time and a new apartment with a lovely little patio for my orchids. As a housewarming gift, I've decided to treat myself to an orchid I've wanted for a long time.

But I can't find it anywhere! Does anyone know where I can find Oncidium onustum/ Zelenkoa onusta? I've checked my favorite sources, a couple I've never heard of, and I even searched ebay (which I don't trust at all after a couple bad experiences). Suggestions? Thanks in advance!

The Orchid Trail here in N.C. has a bunch of them, many of which were in bloom when I visited last weekend. They looked healthy and tempting to me, but I was able to resist temptation because even as small as the plants grow, I knew I'd have a tough time finding room for them.
