Eppendorf Patchman

I am thinking about getting an “Eppendorf Patchman Micromanipulator” for injections into C.elegans gonad.
Has somebody experiences how it performs for these purposes?

Thanks for help,

Eppendorf Patchman Micromanipulator is more expensive, they said the patchman was more popular for patch. but our lab used it.
or u can try the TransferMan or InjectMan. they can directly link to Eppendorf FemtoJet .
maybe u can ask for the company for some advise, i used the patchman and femtojet well.
