We're looking to virtualize a few machines with the hope that we can:

a) Take "snapshots" of a machine to use as backups

b) Implement a system where if the software/hardware fails, we can quickly and easily load up an recent snapshot on new hardware and replace the failed machine with a new one.

As always, cost is a concern- there's only 3 or 4 servers we're going to do this with, so we don't want to drop $50,000 on this.

I'm confused by all of the different virtual machine offerings. Which one is does what I want, and does it easily?
