Suggestions for arm to replace VPI 12.7

Following some further research, I decided that there aren't any good choices to replace the 12.7 arm unless I also make some modifications to the plinth. In short, too much work and expense. So, I decided to stay with VPI, and have purchased the 12" 3D printed armwand. It should arrive in a few days, and I'll add some comments about it after some listening.

Follow-up post: in a few words, the 3D printed arm is SUPERB! I can hardly believe how much the 3D arm improved the sound of my system.

Guys, FWIW, I'd recommend getting the 3D-printed arm before buying a new (upgraded) cartridge. The printed arm is such a significant improvement over the metal arm that it will do a much better job of showing your new cart at its best. In my system, the 3D arm has been one of the best upgrades in the past 20+ years.

I traded my 12.7 arm in to VPI (dealt directly with Harry by E-mail) and got a replacement 3D arm for $1500. I don't know if VPI does this routinely, but it's certainly worth asking.
