I've been using a Twin Wan Router XC-DPG502 by Xincom for two years with a 
Qwest DLS line and radio network via http://www.digis.net/.  The Digits was 
the only type of broadband available when I got the house but a few months 
later DLS was added.  It has only been in the past few months that comcast 
cable service was turned on to my neighborhood (new house) and I plan to add 
that and drop the Digits service.

The DLS is a 1.5 m unmetered connection and digits is a 1.0 m metered 
connection.  My son did a lot of gaming so I had it set to broadband share 
80/20 to keep the Digits under 3 gigs of xfer per month.

The downside, some software applications fail on a dual wan router.  For 
example eSignal stock charting software crashes claiming that I'm trying to 
run two versions of the software.  The company has no fix.  The see requests 
coming from two IP address and assume you have two copies running.  There 
might be a way to always force an application to only use one route, but I 
haven't done the research to figure it out.  As a consequence, I've had to 
reconfigure my router to fallover mode with the DSL as primary and the Digits 
as the fallover if DSL goes down.  DSL fails or goes to a craw about every 
other month and I do a quick reconfigure to make Digis the primary for a day 
or two.

I also have had problems with DNS requests.  The router gives out a DNS 
address to all the computers on the system (DHCP) and requests comming from 
computers to the router cause an address translation to the right DNS 
depending on which of the two lines the data is being routed.  Sometimes this 
hangs and requires a reboot of the computers.  I ended up putting the qwest 
DNS address into the computers directly and this problem went away.  When 
quest dsl goes down, the DNS servers are unaccessible but the computers seem 
to go happily along somehow getting DNS service from the Digis.net servers.

When my children with portables come over and use the network a lot, 
eventually they run into this problem as well but I just have them reboot 
instead of trying to configure their computers specifically for my network

With connections only as fast as 1.5 M, I didn't see any advantages to gigabit 
yet on my home network.

I've administered Unix boxes before and I didn't want to deal with configuring 
linux for this.  In any case, I have a utility room where all the electronics 
in the house converge and where I did all the wiring for ethernet that goes 
to most of the rooms in the house.  To use a linux box, I would either have 
to have a dedicated box in the utility room or have enough cable runs to the
