Internet loadbalance appliances

We have an ISA server and two diff. ISP connections. Currently we use
three old Cisco 2500 and 2600 routers -- one for each ISP and a third
as the loadbalancer behind the two edge routers. It has worked quite
well for us except that 1) it doesn't detect brown-outs and high
latency 2) it doesn't detect a failed link further upstream inside a
carrier network.

I am looking for a smarter, low-cost, hardware solution right now.
Beside buying higher-end Cisco and implementing their more complex
protocols, I am also considering Linksys RV-082, Astro Corp Powerlink
Pro50, Zyxel Zywall 70, xincom XC-DPG502 Twin WAN Router, Alvaco
OPTIQROUTE 2120. Some of these are 200-300 bucks and some at around
1000.

Does anyone has any experiences with these devices? How effective is
your device in detecting brown-outs and remote link failures? How
reliabe is your device?

Any comment will be greated appreciated!
