Although, it's not what you need you still got a fairly good deal at $15- As cheap component DA's start at $40 and up. I'd hold onto this, as it may come in handy in the future. Especially if you want to run an HD video signal to other parts of the house. Of course, you can run composite or just audio signals through-out the house as there are many applications for this gizmo.
Anyway if you're looking for a basic composite or s-video switcher, do a little digging at closeout/bargain stores (like big lots) as you can often find them (with 3 or 4 inputs) for $5-$10. I picked up my last RCA switcher for $7 bucks in a wal-mart clearance isle.
Do not go to Best Buy or other big box electronic stores looking for a switcher, as you'll often pay a minimum of $20 for one.
