Hi Shane,

Depends what kind of thing you're looking to do with it, really. If it's for personal use, or for small office use, go for the Cisco 857.

For anything bigger, go for the Cisco 1841 or 2800-series with WIC-1ADSL.

If you're just starting out with Cisco routers, and are just buying one for home use, have a look on eBay for one of the older 800-series routers - the 827 and 837 are very cheap and are very capable routers (I've got an 827H, which is my internet-facing router).

Hope this helps!

Kind regards,

Graeme
