what platter are you using there? i have an Aries ver.1, and if i had an upgraded arm (10.5), and an isolation base such as yours in black mica (to match the original plinth and to save money) that would also be a nice package.
this post definitely inspires my imagination, although my ultimate VPI machine was the TNT-6 with a super-platter (which had the dual-motor-flywheel assembly from the HRX).
Having said that, your project is a very nice example of a compact and
very elegant machine, and your isolation system seems to work extremely well.
Spending 15-20 grand on a table might be ok but i like this approach even better.
