There are some really good RAID Primers you can read up on, like this one 
from Intel:
http://support.intel.com/support/motherboards/server/raid_info.htm

or this one from LSI:
http://www.lsilogic.com/products/stor_prod/raid/backgrounder1.html

or this one from Adaptec:
http://graphics.adaptec.com/pdfs/ACSP_RAID_Ch4.pdf

My $.02 worth is the Intel and Adaptec SCSI RAID controllers seem to work 
really well for us, but I don't have much experience in the IDE RAID realm 
yet with the exception of the Adaptec/Intel SATA RAID built into the ICH5R 
on the new S875WP1 server board that isn't yet supported under FreeBSD 
(might want to stay away from that one for now)... Probably something from 
Promise will suit you fine. At the low end, if it works, theres not going 
to be a lot of difference among controllers.
