Look for references by Kinkel. I'm sure he has real figures.

I very much doubt the 'enhanced' RT's are any better in the fidelity
dept. Given that microarray labelling kits are incorporating Cy-dUTP/C-
dCTP or amino-allyl dUTP, the mutation rate may be quite different (say
due to stearic hindrance by the Cy analogues) to using straight dNTPs. I
suspect it is something that, like you say, could be being overlooked.

On another note, do you subscribe to the microarray listserv via
yahoogroups? I am supposedly subscribed but have had nothing at all for
at least a week, other than the e-mail saying I am subscribed.

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
