For less than $70 per exchange I would be jumping all over it and maybe would even make another deposit or two.
Even at $239 ($159 if I exchange into a Vacation Villas affilliate) I can usually find 1 or 2 exchanges per year that I couldn't get even with the MF's for the points plus the exchange fee plus the RCI membership fee and every other year combine fees. These were my summer RCI exchanges this year most made 20-13 months in advance, a 2 BR on the beach in the Outer Banks mid June ($600), a 1BR ocean view in Ocean City, MD late June $539, 4 BR Summit in Massanutten in July (the $104 resort fee really impacted that one but even with it my all in was around $600), 2 BR Wyndham Great Smoky Lodge in August) $620.
