First of all, that is the Aramith Crown Standard ball set.
New, those are, IMHO, one of the best values from the fine folks in Belgium - Saluc/Aramith all the way. They clean and polish very well as well as hold up to rigorous play - if played on good equipment (which can be said for any ball set).
A google search will get you to numerous reliable retailers - you can't go wrong for the price.
Ebay all day long at $90 incl shipping. NEW
The balls in the pic "appear" to be chipped - most likely from pocket nails/screws. Not even close to being worth $50 in my opinion.
