Is a WiLs. Aloha Sparks 'Halloween' an oncidium?

[greenpassion]

I've got to stop doing this. I get onto Ebay and am sunk. So yeah, I have gotton another one, this time I think it's an oncidium. No, no pics yet, no blooms either, just "a bloom size orchid" In the photo on line it looked like some sort of ocidium, or maybe another inter generic one. ?? If anyone out there has one, what is the culture? I did get some info from the grower, but I trust you guys way more. I'll google it, just wondering if I'd get a quicker answer here...
