If you could get it for $500 that would be a decent deal. Problem is, as others have said, the parts are not available anymore and they're expensive to fix with the parts that still are available. Something as simple as bypassing the pre-emphasis requires a whole separate card (gee guys, a switch somewhere wouldn't do?) where you can do it in software on any modern processor.
Had one on the WERS 128k stream, with the flat output card. Assuming nothing has changed in the past 2 years it's still on there. Sounded pretty good flat, they fell apart on the HF limiting anyway. All the highs turned to mush and it got too dense, no matter how you adjusted it, compared to the newer Omnias, Orbans and Wheatstones that are out there. Last I knew, WERS has the original Ariane in front of it. I opened the "window" on the wideband AGC pretty far to let the Ariane do most of the leveling.
For the FM and HD, they had limitless amounts of low end. They did sound good during the urban programming. With the regular daytime AAA format, there was no way to get the required top 10 market loudness out of them without the density going WAY up. Did the best I could with the tools available, but with those boxes you were stuck with the sonic palette at hand.
