Btw the Shindo built-in MC stage is optimized to work with SPUs... and does an amazing job with them. You can get the SPU GM Classic for about $650 these days I think.
Of course you also need to figure out whether your Blackbird arm is up to controlling the high weight and low compliance of the SPU cart.
