VPI periphery record ring for VPI Scoutmaster

I just bought a Scoutmaster with Sig Arm upgrade, weight, ring, and VPI IC's. No SDS or HRX motor as of yet. Obviously the SDS is next, but I'm wondering how big of a change the HRX motor really is once you have all the other stuff? $1500 is a bit salty for the motor imho. You really don't have a choice but to buy a new one (no resales).

Also, any recommendations for a cartridge with this rig? Mostly jazz, acoustic. System is Wadia 861SE GNSC, Joule OPS2, LA150, VZN-100's, Merlin VSM-MX, Sound Application Reference LineStage filter, Cardas GR cables.

Thanks all. I've considered the various Shelters, Sumiko Blackbird, but wasn't too aware of the Celebration. Is it a similar cart to the Blackbird (only better)? I'm not to familiar with current generation of Denons though I had a 103D long ago. I know I need something with a somewhat warm (not analytical) tonal balance for the Merlin setup.

After several conversations with Mehran at Sorasound, I ended up with a ZYX Airy3-X-SB. We'll see how it works out once the Scoutmaster gets here, but I'm really looking forward to being back in the analog biz.
