For those that are interested, the cheapest on ebay is $69 or best offer for just the zoom eyepiece.
I payed nearly $60 for mine and nearly $22 for the Vite 5x Barlow about a month ago, never used them. Needing funds to get our car back on the road.
They do sell the identical EP under Skywatcher name (unbranded) and Seban, possibly others too and you could pay up to $159.
