Cartridge Under $2K for Interspace Arm/Deck

I'm looking for suggestions re cartridge for Nottingham Interspace tonearm/deck in the $1500 to $2000 range taking into consideration compliance/mass/resonance/etc. Thanks for your help.
Dynavector XX2 Mk2!! Although I have heard it on a Spacedeck/Spacearm combo.
The Grado Reference ($1200) is a wonderfully musical cartridge, although I can't attest to its compliance compatibility with your Spacearm. I've also heard the Shelter 901 which sounded very good (although, in my system, I prefer my Grado).

Absolute Sound mag also recommends the Sumiko Celebration ($1500) and the Lyra Helicon ($2k). And if you want to save some money and still get a great performing cartridge, you should audition the Shelter 501 Mk2 ($850).
The Space Arm can handle quite a few cartridges, including the ones mentioned already and many others. Can you describe your musical and sonic priorities?

It's your money so you might as well get something you'll like, rather than just something we like!
Dear Vtl: I agree with Sdcampbell about the Sumiko Celebration. This cartridge is a great performer and beats several other cartridges that have 2-3 timews its price. Highly recomended.
Btw, it is a universal cartridge and performs very well on any kind of music you like.

Regards and enjoy the music.
I like the van den hul frog which you can get for about 1k. I use on a michell gyrodec with RB300 arm. I have not auditioned many other cartridges however
