The ones from ORA are expensive, but I didn't think even their best ones were going for that much anymore. There are some imported ones that are down in the $50-100 range now.
The most recent ones from ORA that are going to be the most expensive are the snowflake (all white, maybe with color on the fins) and those are/were going for $800-1,000 per pair. I think they came out with something since them though, maybe a solid black.
