QoS and Maximum Simultaneous Connections

[Scooter92]

I'm not sure if the filters on the router charts are off but I'm trying to get a router that supports automatic QoS and a lot of simultaneous connections. About 3 days ago I used the router charts and the most cost effective one was the DIR 655 by Dlink. Now I did it again just to pull it up and it doesn't even know up! The new most cost-effective one is the Cisco-Linksys WRT320N. So my question to all of you people is which one is better for what I'm looking for!?
