A CC is a basic tool in any woodshop, and you should have one. And perhaps if you just have one project in mind then it is the only power saw you need. It is not, though, the best tool for anyone really planning on doing furniture. And not a track saw. You could do it all with a nice Nicholson hand saw (e.g., Roy Underhill on the Woodright's Shop), but you will do better work, safer work, and have more flexibility with a table saw.
Precision miters and other angles, dado, rabbitts, mortise/tenon, slot cuts, and not to mention small detail cuts like shoulder cuts, can all be easy done on a table saw, and none done easily, safely, or at all with a CC or track saw. A reasonable table saw with a really good blade will allow you to make sufficient quality cuts to edge join/glue boards. Now, you could do all this with a CC, a router (and bits), a joiner, and a gazillion jigs. By the time you invest in all that you could have had a nice table saw.
Go to CL and buy a used corded CC for $50, and then spend $200 on a used table saw. A 113.*** model Craftsman in good shape, or the other links posted in the thread. A $1000 Unisaw or Powermatic would be great, but at this time unnecessary.
