Brzilian is right, HS 2002 is Sonar without some of the whizz bangs but easily sufficient for most amatuers...like me.
CW 8.0 was limited to just a few tracks because it was a demo package for $20, I used to have it before upgrading to HS2002. It was also slow and had latency problems. There is no track limitation on HS2002, only the natural limits of your set-up. So go for HS2002, it will be the best $50 you have ever spent (trust me, I'm a salesman!)
Hope this helps.
