Which CD changer fits the GV?

I'm looking at getting a CD changer for my GV, I see that there is one available from Clarion with Suzuki stamped on it for around $400. If Clarion makes the one that comes in a zuk, wouldn't they make one (without the 'S' stamped on it) that would plug right in? I see several on e-bay, the Clarion DSC625 for example, for much less moola. Any ideas?

Thanks!
