For years I had been a user of Xara 3D - I got a working copy when I was a subscriber of PC Plus. I made my website's logo with it in fact:

I wanted to install it in my current PC, but I can't find the old CD where I got it from, so I went to Xara website to see it. It's just US$29.
Before I buy it, I would like to know if anyone has any experience with other similar software. Xara 3D was very easy to use, and watching a demo it still is, but I remember that in some cases the result had a few glitches, like some stray pixels. That was ages ago and possibly they have solved this, but it's always good to hear a second opinion.
