The auction actually listed U.S. shipping as $15, so when I bid, I assumed it wouldn't be much more to Canada.
Now that I've finally received it, it turns out that postage was only $20.30, not the $48 I paid.
Also, here's the auction's description of condition:
"Without box or instructions. System is in Good condition with a few scratches. Comes with pad (not the original, but a core grafx pad) and all hookups."
What I got is a dirty & worn Shuttle and pad (the A/V cables don't look too nice either).
Both look like they sat next to a mud puddle while someone splashed around in it and also have that kinda layer of dirty film something kept in a dirty area can develop over time.
The Shuttle in particular is worn all over with excessive wear in some spots, lots of scratches and some gouges. It's even pretty filthy on the inside of the "Back-Up" port. The transparent 'cockpit' screen isn't as transparent because of all the scratchy wear that's rendered it dull.
Something I had forgotten when I bid, is that he's also the same seller I once bought a Super Grafx from that also turned out to be filthy(inside & out) and worn. I bought from him instead of a japanese seller with a similarly priced SGX because I hoped I might have fewer potential problems.
I wound up eventually selling the system with a proper description of the condition for a lot less than I paid for it.
I also once got one rare PC Engine game from him with a pretty beat up manual and less than described condition overall, but accepted it at the time, since it was the first time I'd found the game on eBay in months. Again, I had forgotten about this too when I bid on the Shuttle.
At the very least, I'd be careful buying loose or non-new hardware from him and take any mention of minimal wear in general as being exponentially worse.
