Ok, before I spend $25 dollars on a 3d clipart of quite literally "a chicken".... can anybody offer any alternaive sites... or even downloads, anything?

I use aspire.. aspire seem to be so closely tied with 'vector art 3d' im not sure what file format aspire 'accepts' for 3d...

so. my question is as follows

Can anybody offer any other sites etc? that might be cheaper? etc
or can anybody recommend any software I can convert a 2d vector into a 3d vector

am I doing it all wrong and need to use a different peace of software?
