Did the OP say he was running servers at all? If there are no servers, 
then any of a number of "dual-wan routers" will handle the problem with no 
difficulty and minimal expense. If he is running servers, these routers 
generally come with built in software to do dynamic updates of DNS, that I 
understand works, provided you don't have unreasonable expectations about 
reliability. Just because some institutions can't stand 5 minutes of 
downtime doesn't mean there isn't a legitimate use for facilities that 
suffer 5 minutes of downtime several times a year.
