Why so many wilson alexias for sale

One if the most overrated speaker brands there is. Not attacking anyone but heard them so many times and was never in the slightest impressed. Heard hundreds of cheaper speakers I would buy over any Wilson.

"Don't look a gift horse in the mouth."   I never understood the literal translation of that saying, but it seems like like an appropriate time to use it.  Wilson is a high quality product that I never really liked.  They are dry, clinical, and boring to me....  Having heard them about a dozen times at shows & dealers, I've been truly impressed only once (considering the price).  But if you hear a pair, and like them, then buy em.  In the right room with the right amp, I'm sure they can sound great, if you like the Wilson sound.

the saying translated from another language is roughly:
"The teeth of a gifted horse are not for the counting"...
meaning: 
Since the age of a horse is determined by it's teeth,  you just appreciate it even if it's old and on it's last legs -> even if a gift is pretty much worthless you should still appreciate it since the intention of the gift giver is to give you a present...
