Bump on this thread!
I've just acquired an Opus 7 via eBay. Got it for around $150 which is quite reasonable for a set of this quality.
I'm going to pick it up next Sunday. A short drive to Los Angeles. Can't wait to get it.
Here's a picture of how it looks like. Not my unit, but it is the exact same model. I prefer this "modern" style cabinet with the wooden bars on the grille.
