Capillary electrophoresis equipment

[Royston E. Carter PhD]

Hi,
I am posting this for a friend planning to buy a CE system.  Currently 
four systems are being considered:
	Biorad
	ABI
	Hewlitt Packard
	Beckman
Does anyone have experience of any of these systems? Any 
recommendations?  The system has two requirements, routine QC type 
analyses of a complex protein mixture and the collection of individual 
fractions of these components for further analysis e.g. peptide sequencing.
Any comments on reliability and user friendlyness would also be usefull.
