Firewire 410, Firewire Hubs Options

[tig66]

I'm thinking of purchasing a Firewire hub, due to the amount of different firewire peripherals that I have.. my question is, does anyone know if Firewire hubs cause any problems when used in the audio firewire connection?
My Firewire 410 according to M-Audio needs to be at the end of the Firewire buss, but unfortunately I only have one port on my Powerbook Ti 500 + I also have a 250Gb firewire800 drive with only 1 firewire 400 port, which more or less narrows down my possibilities.

Also, if anyone can recommend or offer any advice on decent 6 port firewire hubs as well, as I can't find any reviews anywhere ??

Thanks
