Summary of micromanipulators recommended for DNA microinjection:

I asked for recommendations on micromanipulators for C.elegans DNA
microinjection (before I left for vacation two weeks ago).  Below are
excertps of the responses I've received so far. 

MAIN CONCLUSION:

For my purposes, the main conclusion is that folks have been satisfatied
with relatively simple manipulators, such as Narishige's MN-151 model which
costs about $1500 (before this week's price increase), as opposed to the
more expensive models which can cost thousands more.

Curtis Loer also sent me a summary of comments he received earlier in
response to a similar survey.  I've extracted those comments relating to
micromanipulators.
