I'd say mid-high $xxx. Somewhat pronounceable, rhymes with mazda...j/k. The Z makes it hard to do any acronyms but llll's are selling decently right now.
I'd say high $xxx as well. It is easily pronouncable, .com, and all letters. If I were you I'd hang on to it for a few years and see if the value increases even more
I was thinkin the "oz" could refer to Australian. A search of google came up with this: DA Information services supplies libraries and individuals throughout Australasia with technical and academic books at country of origin prices.
