I'm soon going to begin studying for the CCNA exam, and I want to start acquiring the appropriate hardware that I will need to start learning the basics (obviously I'm buying materials besides just hardware, but I do learn best from hands on things). Can I get some recommendations as to what I should buy, as well as where I could buy it for a decent price? I don't have a huge budget, but I do know it is important to my future so I'm willing to spend some money.
