I see the 160mhz models up from time to time. Don't (and never had) one of any stripe, unfortunately 
If it's for OS/4 use you're after it, what you'll wind up paying would be better spent on a Samantha board in terms of raw performance, although those are not without their own issues.
If you ever see a DMA-fixed, USB-fixed, properly cooled and new-battery installed Teron (A1) board for sale and don't have to mortgage your house, buy that. They're underclocked to 933mhz all the way down to 800mhz, but from what I've heard getting them running at 1ghz isn't impossible and will give you the fastest OS/4 platform period.
Pegasos II is the fastest and most stable OS4 platform available, full stop.
