Ivan Stewart Replicas and Best Price for Real Ones?

Someone on a thread mentioned the replicas, but can't remember what brand or model they were. What were those and are the good wheels? What's the best price around for real Ivan's? Cheapest I've seen so far is $198 on trdparts.com.

Also, anyone know the part number for the improved ones? I read about problems with the older batches.

Thanks.

Found a website that lists the Niche Throttle/IS replicas. But it's a strange website.
