Hey Speck! I found another spelling/syntax search irregularity you might want to iron out.
There are four (normal-size) sculpts of the Mad Cat Mk II, but two of them are named "Mad Cat Mk II" and two of them are named "Mad Cat MkII" (with no space after the "Mk"). It makes searches only turn up one or the other, depending on how you typed it.
(There's also a difference between "MK II" and "Mk II" (k lower case), but the search engine doesn't seem to care about caps.)
