Solved automatic failover for a border firewall

Sorry, this is not a FreeBSD specific question but I figured there are knowledgeable people here who might be able to help!
Code: 
 private
 ip net (192.168.x.0/24)
    .   +---------+
    |   | border  +--- public ip to isp1 (fast connection)
    +---+ gateway |
    |   |         +--- public ip to isp2 (slow connection)
    .   +---------+
See the above set up. The border gateway needs to switch over to the slower secondary public connection if the faster primary connection fails. Any existing connections will break at the time of switch over but that is ok. This is for a friend who is not tech savvy so it has to be something that just works once set up. Is anyone aware of a turnkey or commercial router that can do this? Thanks!
 
Thanks! Will look at Juniper offerings. As I understand it, link aggregation wouldn't work when interfaces are connected to different ISPs.
 
A really, really simple solution would be to run a cronjob every couple of minutes that will ping the ISP gateway. If the ping fails you switch the default gateway to the other ISP.

gateway and some well known ip like 1.1.1.1 (the gateway might work but the internet/uplink might not)
you may need a static route and or multiple fibs
