router for two separate public network links

I have two separate data connections from local carriers, Qwest and Cox Cable.  They both hand-off cat 5, and qwest has one public interface homed on the circuit, and cox has 3 public ip addresses homed on the circuit.  I want to put a front end device that will provide fault tolerance or fail over.

inside the networks I have VOIP and data on one side (qwest), and business to business applications on the other side(cox) and I understand if I had true fail over I would have to engineer the applications to adapt to any changes, but primarily I am looking for a low-cost router that would provide failover / redundancy so that my internal network could access the outside world if one circuit or the other went down.  I also would like some external clients to be able to access my internal resources regardless of whether or not one or the other went down (dynamic DNS).  If you could recommend a router for the front end and possibly a strategy that would be helpful.

please note that this is all the same physical location and I want to leverage the fact that I have two ISP links in the same office.

I've heard some good stries about radwara:
Don't have any experience myself though.
Check out the Linsys / Cisco RV042 router.  I used it in my office with a DSL and a cable connection.  Worked well.

I've been using Cyberoam for Internet failover.
SonicWall.  Still have a TZ170 from a few years back that can handle bonded T1s and an ADSL with no problems.

Also have a dual-WAN Netgear FVS336G, which is lower in price than the SonicWall.  Haven't explored many feature yet.

Any of the smaller Check Point or Juniper offerings will deliver on multi wan connections.

My money would go on an SSG5 or SRX100 as these are small SOHO appliances but have the full blown power screenos for the SSG and Junos for the SRX and thus the networking ability to manage multiple wan connections
