LOL i'm not rich man, I just worked for a big company in south africa, they had both pcad2001 and spectra. I actually got a professional 3 day course from PCAD representative and learned spectra on my own.
I also used it for one of my projects as an excercise and it was well worth it, you go from schematics to pcb to routing in 1 or 2 hours at the most and everything right first time.
Track widths are very easy, you just define them in the schematics, you edit the nets and change the properties like I make the power nets 40 mils, small signal track width 8 mils in the schematics and the auto router does them straight away. there are lots of extra parameters you can define in specctra itself also but the best thing is when you define them in the schematics.
Another great advantage of specctra is the autoplacement of components, I experimented with it on a small board and it was so great. But for huge boards it makes component placenent and routing a breeze.
There are lots of companies who use PCAD2001 and spectra services, you just send them schematics and they do the component placement and routing very quickly and professionally which is much cheaper than buying the product itself.
But as I mentioned before you can use the trial version of pcad2001 free for 30 days, if you can't afford it just format your hard drive and install again for another 30 days.
