I'm doing this to avoid the fees after all. Gotta look at total cost of it here. And as typical for less "popular" systems, Turbo stuff had horrid regional distribution. Much harder to find in certain parts of the country...
Almost every single NEC system or game that changes hands in the US these days is purchased on eBay or in some other way over the internet and sent through the mail. It was that way before eBay, with TZD, Die Hard, Buy Rite, etc being the only places to buy stuff in the mid 90s. In Japan its different, but almost nobody in this country is going into a store and buying this stuff. Therefore, regional distribution kind of doesn't apply to these kinds of things like it applies to...automobiles or arcade machines, for example (which people don't like to ship, so they stay semi-local).
A good clean Duo is about $250 now I think, but this one doesn't have the correct controller or a HuCard slot door (WTF happens to these things!?). The pic isn't very high quality, so its hard to tell, but the system also looks kind of grungy. On the plus side it has the original power supply and what looks like the original AV cable (as opposed to that piece of shit TZD sold) so I'd say $150 or so, max, for the system.
