[rescue] Best options for U160 SCSI on Solaris / SPARC?

I have a small Sun Cluster of a V210 and V240 that are sharing a  
single S1 array. I've recently procured a second S1 array and I would  
like to have both of the systems use the on-board SCSI controller to  
access the original S1, and add a secondary SCSI controller for the  
new S1. This lets me migrate from the SVM RAID on the original S1  
which is managed by Sun Cluster to a new set of ZFS pools on the new S1.

I've looked at the variety of SCSI options for SPARC systems, and  
while many of them are readily available to me to use, they all seem  
to only support Wide or Narrow, and not the U160 UW that the S1 is  
using. It seems like what I need is a X6758A, "PCI Dual Ultra3 SCSI  
Host Adapter (LVD)". Since those seem hard to come by on eBay and are  
rather expensive when I do find them, are there any better (read:  
cheaper) options?
