Zbrush is awesome but takes a bit of getting used to if you use normal 3D software (took me 3 days to work out how to save stuff!).
The cheapest option I think is Hexagon 2 at http://www.daz3d.com/program/hexagon/, it is supposed to be as good a modeller as Modo, some say better, although the painting isnt quite as good. It is also half price (normally $149 i think) at the moment if you become a platinum member (for $29) so a pretty good deal I reckon (no I dont work for them!) and theres also a demo.
