The WAN port should be capable of at least 10mbps. Most likely it can handle 100mbps. The WAN port uses the same protocol as the LAN port, so the port itself shouldn't be a bottleneck, expecially not for the Internet.

Bandwidth is usually not the issue, it is the processing of packets that will kill the router.  The question to be asked is what type of traffic will you be routing?  Web browsing and email will not be an issue, however if your running web servers, mail servers and DNS servers for public access or you will be using it for VPN acess or you have an extensive access list, you will probably want consider a router with more memory and processing power.  There are Cisco 2600 and 3600 series routers available on the cheap.

The 1750 will only support 4.35Mbps when using Fast/CEF switching.  You may want to look at replacing it with a 1800 or 2800 instead.  Or, if the 5Mbps handoff is ethernet, you can always plug it into a LAN switch which will meet the performance requirements.

Around $750 for an 1811.  You can probably find cheaper.  If you want to go cheap, you can use a 2621XM which you can find on eBay for about $150 but keep in mind you can't get support on it or upgrade software.
