I can vouch for two types of Belkin hubs, both with a lifetime warranty.
I have used a four-port hub with a power supply with OS: XP, Vista and now Windows 7, successfully. Model number: F5U231. I have also used a seven-port hub with a power supply with OS: XP, Vista and now Windows 7. Model number: F5U237.
I have had two of the four-port hubs fail after five+ years of use and all I have had to do was call Belkin, get an RMA number, ship it back along with the power supply and they have sent me a new, in-package, hub with absolutely no problem.
I am sold on their hubs with out a doubt!
