Thanks very much for the informative numbers.  If the price of
the EV4 and EV5 Alphas drop now the EV6 is on general release
this will make it a very cost effective solution (I see that
a reasonably configured dual EV6/500 MHz runs for about $20k
at the moment so this isn't really an option for a lab on a
budget).  I've found lightly configured 21164A/533 MHz machines
for well under $2,000 so these would give the others a run
for their money.
     Roll on the 1 GHz EV7...!
