Just thought I would point out that a 2-channel 3ware card is about the price 
of a single 80GB drive.  (i.e. $130 US)

I love the 3-ware cards and they are not cost prohibitive in my opinion.  My 
only problem is I wish the failure/rebuild process was more automated than it currently is.

Obviously, LVM and MD should still work together regardless.
