GPIB Ethernet gateway recommendation

["Jiro Fujita" <jiro.fujita@gmail.com>]

Can anybody recommend me a good GPIB Ethernet gateway for using with
EPICS?  I will be using it with a Linux machine working as soft IOC.
I know Aglent E5810A has been discussed on Tech-Talk, but I am curious
if anybody have a recommendation on a device like that.
Also, if anybody have a information/suggestion on using one of these
device as oppose to using a PCI GPIB interface card, that would be a
welcome.  In particular, I am most interested in the reliability of
GPIB Ethernet gateway as opposed to using a PCI card.
