Yes, I know Bruce (and agree).  But this is not a professional IT mail list.  
It's a hobbyist mail list... which usually equates to "frugal" ;).  So I just 
framed it as such... Remember.. when some people think "RAID", they're 
thinking embedded mobo SW RAID, el-cheap-o PCI RAID-1 (only) cards, or even 
(gasp) software RAID.. hehe..

But yes.. if you're going to "do it right", and don't want to buy one of 

then you're going to spend a pretty penny setting up your own, large, high 
availability system.  For example... several friends of mine at work who need 
a multi-TB SATA array (for digital home theater) go with this type of 
setup... easily running into the $1-3000 range after all said and done.
