It will be more of an audio master at this point. Parts for the electrical and CD components for Mk1s are exceedingly hard to get anymore. There's a similarly good deal on the local craigslist where I'm visiting for a complete Mk1 with stand for 800.00 in I assume working condition, but it is a 220v model that will have to be converted. I don't think it's worth fiddling with as it is just a Mk1. But they'll sell the stand for 200 and I might knock them down to 100 and take that.
Best 9000s to get seem to be the Mk2s which have a huge market of replacement lasers out there and still have available electrical parts, while the Mk3 lasers, while still available from B&O, are supposedly no where else once that supply dries up (at least as of several months ago, last I looked into 9000s).
Also, as far as I know, the glass replacements for Mk1s were not just a goodwill thing, they were a full on recall, so I'd imagine if you have one with separated glass (which shouldn't have happened to any of the later units) you could theoretically just get a B&O dealer to replace it.
