Thanks, Dizzy Bull and vhs!
Yeah, I checked out all the places you mentioned and some underground/subway-ish spots in myungdong.  I found records, but they were the kind that we already mentioned.  And yes, vhs, almost all were priced at 5000.  I found a couple places where the korean records (mostly early 90s junk) were being sold for 3000, though.  Most of the non-korean records were of the sinatra/paul anka/pop vocals variety, with some 80s heavy metal.  And some leo sayer.
One interesting thing - one record store in myungdong converted one of its floors to a japanese language cafe (?) so I was digging while a bunch of japanese people were watching me.  Kind of uncomfortable.

Ha.  I'm sorry to hear that.  But busan is known for its seafood (if you're into that), so you should check that out.
Thanks again, fellas.
(I'll let you know if I find anything.)
