They were much less common on the XJ than many other SUVs from the same era though (including the ZJ/WJ) and are somewhat difficult to find (and tend to go for relatively high prices). If you keep checking EBay they come up every now and then (it took me a couple months to find mine) and usually sell for around $75-$100.
They may have been discontinued by now, but when I checked a couple years ago you could still get a new one from the dealer for around $400 (ridiculous, I know).
