POE gear used to be all over the map in terms of quality, capability and reliability but they seem to be getting a lot better. I see more and more of the lower-end products including sufficient information about the switch's current ratings and have usually found them to be accurate enough for government work. Whether POE phones or WAP/repeaters, I just grab their power requirements and figure out how many of them I can drive off a given switch and then subtract one to be safe. Sometimes you can't drive the number of devices the ports support but you can make it work.

Other times I insist the customer spend for a ProCurve. =)
