How to add more firewire connections

[Grampa Joe]

I have an iMac G5, Rev. A that has 3 USB ports in the back. I want to add a few more because it is awkward plugging any more USB devices (such as my flash drive).
Is there a cable or something that will allow me to have multiple USB ports?
I plan to upgrade to Leopard when it shows up, so maybe there is an external hard drive I can buy that will have extra USB ports.
Thanks for your help!

Something wrong with a powered USB hub?

Sorry to be so ignorant, Sun Baked, but what? A powered USB hub? Can't say as I know about that unit. Whoops, just found one. There is a Linksys USB2HUB4 USB 4-Port Hub on Amazon. Is that what you mean?
I can't thank you enough for turning me on to one of these little gizmos. Sure hope it works with my iMAc.

I ended up getting the Kensington DomeHub USB 2.0 (7 ports) Weighted Hub 33118 from Amazon. Thanks again, Sun Baked!
