SAS controller for FreeBSD

We have been using ZFS under FreeBSD for a while, and are very pleased,
but are considering building a system with SAS drives, in the hope that
they will be faster (any truth to that?). I am assuming that I should look
for a non-RAID controller, but I can't find any SAS controllers that don't
claim to do RAID and are on the FreeBSD compatibility list. I have always
thought that using a RAID controller for a non-raid partition was a bad
idea, since it limited ones ability to swap controllersm, and presumably
if we are using ZFS for our RAID we don't need another level of RAID
provided by the controller. Is that prejudice justified?
There are some SAS RAID controllers that claim to support FreeBSD but I
can't tell if their JBOD mode is a true pass-through, or leaves some
undesirable junk on the disk.
So does anyone have a recomendation for a reasonably priced SAS
controller? We aren't looking for anything fancy at this point.
