Doesn't quite answer your question, but if you are considering ever upgrading your Adat setup to HD24 (as I did), it may be worth noting that their BRC works quite well with HD24. Ebay should give you clues to current prices. Mine was only $60, but that was an old, untested unit bought in Tokyo, where older gear can be found real cheap on occasion (Japanese love their 'latest models').
Actually, it seems like BRC's are still selling in the $250 and up range. The fact that they do work with the HD24 has helped them retain their value. They are actually worth more now than the ADAT's themselves
