G'day Shankyrhodes,
Harvin is correct that VC is expensive for what it does.
What features are you looking for?
If you are able to shutdown VM's for short periods while you work on the ESX, then an OpenE iSCSI is all you need.
So long as the VM is on the shared iSCSI target, you just shutdown the VM, remove it from the Inventory, browse the datastore on the other ESX, and import the vmx config.
VC would allow you to cold migrate (ie shutdown) VMS from one ESX to the other if you have a shared data store (ie DSS iSCSI) and it is also nice for templates. (Though Harvins solution is also fine if you don't do them often).
It also gives you longer trending for performance, and I think that would be abuot it in your scenario.
