Lab Equipment

in CCNA & CCENT
If I were going to set up a lab to prepare for the CCNA exam and get some good hands-on experience what model of router and switch should I purchase? I want this to be a fully functioning lab and I don't want the equipment to be out of date or end-of-life in a month. Any input you can give would be appreciated.

depending on your budget get 2600's routers and 2950 switch
if u got alot to spend get 3620 routers and 3550 switches.. these will be a long time before it expires
Or you could buy the new Boson Netsim CCNP that is in Beta right now. It is currently 250.00 but it will be right at 500.00 when the full version is out...if you buy now you get the upgrades for free. I bought a copy for the times that I do not have connection to my rack at home. I am pretty impressed with the new version. Not to mention all the labs you can design your self with it. I didn't like earlier versions as much....but this one is pretty cool...
