If your looking for free and good then it would be worth taking advantage of as many trials/freeware versions as you can. Sketch-up is very user friendly but I find it lacks all the tools I'd expect from a 'professional' package - but then it's free so you can use it along with other software.


If you are looking for a 3D package your choices are more limited and more expensive. ZWcad comes I've used comercially as a 2D AutoCAD alternative. There are plenty of alternatives to AutoCAD LT, and for a good chunk cheaper, that can do a very profesional job. I think the call would come down on to whether your looking to work in 2D or 3D.
