Finally managed to find a local Mac Studio M3 Ultra 512GB/8TB setup that I’d been searching for, so now I’m reevaluating my current AI hardware setup, including my 2 NVIDIA DGX Spark systems (4TB / 128GB RAM each).

Both units are still in excellent condition and have been amazing for local model work, experimentation, and AI workflows.

One thing I noticed while looking into these systems is how wildly inconsistent the pricing/discussions are depending on the platform, reseller, or region. The differences are honestly pretty surprising.

Curious how people in the AI/homelab space usually approach high-end hardware like this, especially regarding trusted platforms, community experiences, valuations, and avoiding excessive marketplace fees.
