Today I talked with an AT&T Broadband rep while I switched to digital
phone service.  He told me that there is a hidden $10 charge for the
cable modem that AT&T provides.  If I buy my own, I can save $10/month
off my bill.  

So what are the good cable modems out there?  Are there any performance
differences between them?  It doesn't seem like the kind of thing you'd
see reviewed in computer rags.  

I'm currently using a Toshiba PCX1100U, which seems to work just fine.
I have an OpenBSD firewall sitting right behind it with a 10Mb hub
sitting just beyond that.
