Pentax FA*250-600/5.6 - Anyone Enabled?

[John Taylor]

Would anyone happen to be lucky enough to posess  or even have the  
chance to test out the legendary FA*250-600/5.6 Mega Zoom from Pentax?
I'm seriously considering obtaining one I've located, but the jury is  
still out on whether it will perform on digital in the same leaque as  
its little cousins FA*80-200/2.8 and FA* 28-70/2.8.  The price is  
right (so to speak) at slightly over 3K,  but I still have questions.

Thanks,
