Not a bad price at all ($209):

Yeah, I think it's going to be in 8.0, but Scott Long pointed me to it 
saying it would work on 7.2, and it does.  It's in the FBSD svn repo 
somewhere, the tool is "mptutil".  I'm using it without issue on a 
Dell-badged LSI RAID controller:

mpt0: <LSILogic SAS/SATA Adapter> port 0xec00-0xecff mem 
0xfe9fc000-0xfe9fffff,0xfe9e0000-0xfe9effff irq 16 at device 8.0 on pci2
mpt0: [ITHREAD]
mpt0: MPI Version=
mpt0: Capabilities: ( RAID-0 RAID-1E RAID-1 )

There was this thread on -stable recently, it looks like support is a work 
in progress...

It's just a gut feeling, but Highpoint and SIIS seem like very low-end 
PC-modder type toys.  Thanks for the LSI tip though, I'm a bit more 
trusting of them.
