It's hardly off topic - after all, this site is all about making the most of our older machines.

I don't see any places which still carry the 1 GHz Crescendo G4. I'm glad I got mine while it was available. At $100, I would've thought it'd have been pretty popular and therefore more common, but perhaps Sonnet only made a certain number of them and that was that.

If I were you, I'd contact them directly and ask nicely. You never know...
