I don't do much in the way of modeling so can't offer a worthwhile opinion. However if you are considering TrueSpace and you're on a very tight budget, the publisher has TS ver 3 on sale for $99. I believe it's only going to last a few more days so if you're interested take a look at their site quickly. www.caligari.com As someone else suggested, Amapi 4.1 was given away free with the May 2000 issue of Digit magazine. It's not too old so perhaps you can still find a copy somewhere. Amapi's site has an update to 4.15 which apparently corrects some of the stability problems. Can't really say as I have the magazine but haven't tried Amapi yet.
