Will I need to UL list under UL's ITE protocol?

Forgive the stupid question Mike Holt Forum guru's out there:
I'm designing my first AV circuit. It's a real low-power circuit.
Currently I estimate it to be about 3watts total. According to UL's site a middle-powered Class to PSU would be way more than enough for my needs. There are plenty of off the shelf solutions for me that would more than suffice.
I've gathered that using a Class 2 psu in an AV/computing device would simplify my UL listing. Let's say I use a low- watt (WAY under 90) factory enclosed psu for av/information systems that is listed as an "ITE" type psu. Supposing that I follow the application guidelines to the letter and my circuit has a sub- 1A current draw and follow all of the wiring guidelines.
My question is this: Do I still have to list it with UL (or ETC et. al.)? Will it save me any money at all in the listing process? Is there a "fast track" for people like me? Do custom PC case designers have to list all of their products, even though they use pre-approved psus? Or does the unknown (to UL) power draw and wiring implementation of the load circuit mean that none escape the financial burden of the UL Listing process?
