TGCD vs Duo

From Impmon <xxxxxx@tds.net>

I have a fully working TG CD setup that I got way back when Toys R Us were
blowing them out for under $100 and I still have the original box and carry
case.  I do know I'd need System 3.0 card to play some CD games but would it
be easier if I tried to find a Duo and sell the TurboCD set?  System 3.0
card rarely pops up on evilBay anyway.  I can only find 2 in the past
auctions (2 weeks worth) and there's only one on right now for a Japanese
version.

OTOH TurboDuo appears very frequently on evilBay (about a dozen right now
going between $100-$200)

So if I choose to get a TurboDuo, any idea how much a boxed TurboCD would
sell for?  I'm pretty sure I have the original CD manuals but I do have the
original boxes and foam inserts and the original power supply required for
the CD part and System 2.0 card.  The box itself is rather huge, about 2
feet tall by 1.5 feet around.

Thanks.
