im goin to start self teaching myself cicso so when i accually take the course ill have an advantage and can ask questions that wont be covered by the basics. I want to get a router or routers switches, etc to build a small network and mess around. what series and models would u recommend. also how many pcs should i hook up to the network. i havent planned on putting it in my main network untill im comfortable with the software. any insight on this would be greatly appreciated
