[H] Question on managed switches

[Thane Sherrington]

I'm looking for a durable, 24 port switch, and I'm thinking I should 
go managed so that I can set some of the ports to have guaranteed 
amount of bandwidth because occasionally a machine of lower 
importance will go nuts and grab all the bandwidth on my current 
unmanaged switch (at least, that's what appears to be 
happening.)  Does this makes sense, and if so, what makes/models are good?
