Consistent Lambda preps? FAQs anywhere?

[Hong Dang]

Dear Netters:

I would very much appreciate some pointers on CONSISTENT Lambda preps. My wife
is having a hard time getting consistent yield of a lambda clone containing a 
about 18 kb insert. Is there a FAQ on this subject? If yes, where can I find it?
Any help would be very much appreciated. Thank you in advance!
