Redirecting users upon logging in

I have what I thought was an easy problem that would have an easy solution.  Unfortunately....
Authenticated users logging onto my site have all been assigned a role: Administrators, Group1, and Group2. I want each user to be redirected using DestinationPageUrl to an Administrator page, a Group1 page, or aGroup2 page based on their role. Isn't there an easy way to do this using an If...Then statement? All I seem to find is mountains of code.
Thanks,
Oliphant
