Phal. I-Hsin The Big Bang

[Mountaineer370]

This is a longshot, I know, but does anybody know where I can acquire one of these? I believe I've also seen it listed with a couple different cultivar names. (And please forgive me if I've got the nomenclature wrong.) I saw my first one at our society's orchid show last year and fell in love with the colors and pattern of the flowers. It's very unique and right up my alley. I saw another one at my society meeting last month, but, unfortunately, the member who owns it has had it a long time and cannot remember where it came from. I've Googled -- a lot -- and, yes, there is one vendor out there who is advertising them for sale, for a hefty price -- but it is a vendor with pretty dismal reviews, not only here but from many sources, so I am very apprehensive. I'm open to any other ideas.
