I don't think I ever tried that one. Before i got JAWS, I used the WeMedia Talking Browser (which was free). But when I tried to hit the site a few minutes ago, I couldn't connect. I also noticed that cnet no longer had a download of the talking browser.... so I don't know whats up with that.
I have used a few different screenreaders, and they all intepret pages a little differently (what else is new). Mostly, it was small stuff like I beleive JAWS says "image" before reading the alt text for an image whereas the talking browser did not. Many small differences, but few serious ones if I remember correctly.
I know that JAWS is the most widespread, but I'm sure that testing in the IBM one is well worth it.
BTW, JAWS does have a free demo.... the site says the demo lasts for 40 minutes(!), but I remember being able to use the demo past that limit, so maybe give it a try http://www.freedomscientific.com/fs_dow … s_form.asp
EDIT: oh yeah, I'm more than willing to help out with a JAWS test.
