To be honest the only way I know is to see if you can try before you buy. I know not all software producers allow this. TS does have a demo version at www.caligari.com Its now the program I do all my modeling in. You may try the other sites to see if they have similar. Generally you get what you pay for, after that its personal preference. That said you may like to review the free program from http://www.anim8or.com/ Hope this helps PhilC www.philc.net
