Software / hardware watchdogs

I would like to start an discussion on the various types of watchdogs available, starting from the software watchdog available in the linux kernel, to dedicated hardware devices. What are the features they implement, are they worth the money, and generally any opinions on the topic.

What I need a watchdog for is to be able to power cycle, or at least issue a software restart ( in case of a software watchdog ) if an attempt for ssh connection is not established in 60 seconds
