96 well miniprep?

[nikinje]

I am currently trailling some 96 well miniprep kits, mainly Millipore's one and Qiagen's Turbo kit.

We have done our first trial of the millipore kit and have had abysmal yields, it is a low copy number plasmid, but I was just wondering if there is anyone else out there with some experience of any 96 well kits that could let me know the sort of yields you would expect (ng/ul).
