alt Hacker NewsI don't know much about UL but I can say that FCC certification (also technically required) for electronics can range from about $3k to something like $30k depending on what you're doing.
($3k would be for "unintentional radiator" device, i.e., not supposed to be a radio, $30k would be for "intentional radiator" device, i.e., supposed to be a radio)

Because of customs product import rules, that FCC stamp is often not optional. Now if it was a dodgy seller, the stamp will not match the physical devices on rare occasion. =3
FCC ensures a product doesn't cause radio interference, while UL ensures the product is safe to use and won't cause fires or electric shocks. For DIY, your primary concern is UL certification.
