Dual rackmountable power supply?

[Mike Sawicki <fifi () HAX ORG>]

Do any of you know if there are companies who manufacture 1/2U
rackmountable PDU's that take AC from redundant sources?  I have
equipment at a colo that seems to have issues with one of the two
circuits in my cabinets about once a month.  Since it would be a
real pain in the neck for me to retrofit every server with dual-ps,
I was thinking this could be a possible middle-of-the-road solution.
Thanks.
