MONO cartridge under $1k - Lyra Dorian?

I am contemplating purchasing a spare armtube for my VPI JMW-9 arm to use for dedicated mono playback. The new Lyra Dorian Mono seems like a good candidate given its price and pedigree; I am wondering if anybody has heard it or if it is avaliable yet. Also interested in suggestions of other good MONO cartridges under $1k. Thanks.
