I recently upgraded to a Thales Simplicity tonearm. I could not be happier or more impressed. If you want a significant upgrade to your arm I would consider it, or the Thales Easy. Both utilize tangential tracking in a pivoted design, and so if you would like an upgrade that you may really hear I'd consider something substantial like the Thales.
The Schroeder LT mentioned earlier provides that same benefit too.
