I think the questions should be pretty much answered in this link
Sunset Valley Orchids - Catasetinae Culture .
Spidermites afflict Catasetinae leaves... fortunately, each year it gets new leaves, a new chance in the new year. Once those new leaves emerge and develop, watch carefully and treat when (not if... ) they show up.
Price is reasonable - this is a mature plant not a seedling. This time of year, the Catasetinae that haven't already gone dormant just do look rather ratty so don't judge its appearance.
