Lucky for you that placement is easy!
I don't see a CDT3 on the Jay's website-- there's a CDT2 MK3. . . is that what you mean? I know they'll supply replacement lasers but not sure about the actual drive. If I bought the Jay's, I'd want a spare.
@mdrone :
Well, some of it is gone, which is why I don't play my electric guitar anymore (although I haven't had the heart to sell it, yet) and also why I have an SPL meter within reach of my listening chair ;o)
