Thanks for the feedback. An apple centric friend of mine suggested either Apple or Intel SSDs, and nothing else. I didn't get all of the details of why, but mostly it has to do with which manufacturers test for what.
There's another possible route that has been suggested and that's to find a used Mac Pro (desktop). A friend pointed me to a craigslist add for an 8 core machine for $1200. Not as cheap as an SSD, but then I could put all of my drives in the box so that they are right on the SATA bus rather than hanging them off firewire or such like. > I just successfully upgraded my 2008 vintage 20" iMac with a 250GB SSD > and I can confirm that it's a worthwhile effort.
