Excellent router for CCNA/NP practice, good enough for general use

Summary: This is an extremely versatile router. However, it's a very good thing that I have access to a Cisco contract account. My router came configured for voice, and I needed IP. That's easy enough to change, IF you have access to the proper software tools. The 2821's raw routing performance is 87.04 MBps, which should keep up with home internet services up to around 50-60 MBps. Actual speeds will depend on the services/configuration you run on it.
Summary: I bought this router due to the price and it is what we are using in class. If you are buying for a CCNA lab, I would suggest that you buy a couple of WIC cards and cables. It is the only way to practice some of the labs. IOS 12.4 will only get you so far. If you plan on trying to go to some of the voice and security add ons, you might want to find one with 15.1. Don't forget a console cable or a rollover!
