Engine stand options ??

[j.fro]

Ok, I need to pull the M96 from my 996 so I can remove the heads (oil in coolant, traces of coolant in oil).
What are the pros/cons of the stands out there??? I'm not looking for a hoist, just a stand. I've seen the Harbor Freight units @ <$60 and others at >$300. Hopefully I'll only need to use this once for a couple of months.
