The DSL router might support NAT (if it is a router), however many ISP's only provide to their customers DSL modems which generally have no services (like NAT or PAT) on them.
Yes, Cisco does have a layer 3 2900 (specifically the 2948G-L3), but according to the documentation that I reviewed, NAT is not one of the features that is currently supported on that switch. Generally NAT is not a requirement on the internal (private side) of a network. It is generally a feature used in routers and the internet to conserve public IP addresses and share that 1 (or more addresses) amongst a larger pool of users.
Additionally, for a small network like yours, I don't think (without further information) that you would really see a return on your investment in the above layer 3 switch (it lists for approximately $9995US)
The reason that I recommended the PIX was in your original post you did not indicate that you had any kind of firewall protection and that really is stronglt recommended (strike that - an absolute must have) with any connection to the internet. Check this page
www.cisco.com/go/safe for more details on that (specifically the blue print for the small to medium size business, it is a big document but VERY worthwhile).
