Over the top in general are super rare, there are special editions floating around that are rare, Juliet's, Penny's (which have an AWESOME story, if you'd like I could write in another post) are both pretty rare... The thing is, with LUX buying Oakley, they've broadened their line and reduced the X-Metal items down to two models (both on sale and no rumor of new ones) this means the new items will not be as valuable down the road like the previously mentioned items.
