In terms of ATAs, I use the Cisco 186. Awesome little device that lets you customize just about everything, including the ring cadence and the region of the ringback and other tones. My one problem with it is that it puts the caller ID name in quotes.

Like this:

"Cell Phone Wa"
1-360-555-1234

If you are considering an ATA the Cisco model does provide two ports, so two CO lines on the KSU. Also, check out CallCentric for VoIP service. I pay just shy of $15/mo for my local Oak Harbor, Washington DID # and 500 minutes to any North American number.
