Any router, lest it be Cisco, HP, Juniper, Netgear, Belkin, Draytek, etc, can "do" the job. The question is: What does the job entail?
Your description is very basic. Any broadband router can do NAT/DHCP. Any.
You ask the question on a Cisco-owned and managed forum, I give you a Cisco enterprise-grade product to suit your requirement. Unfortunately, I am not a user of other vendor's equipment so my knowledge to them is, at best, extremely limited.
Do remember that Data Sheets are written by the marketing people (any Data Sheets). It will contain very limited technical details. If there are any technical details involved, take it with a grain of salt because the details are either inflated (like bandwidth) and capabilities (as clear as mud).
Prices between vendors and Cisco may be a fraction of the cost of a Cisco product but it is well known that Cisco can do more stuff than other vendors.
