Beautiful collection! Out of curiosity, how much did those boards cost in South Korea?
FC660C was bought in Japan for about ¥22,000
RF 104U was bought in Japan for about ¥20,000
RF 23UB was bought in Japan for about ¥10,000
Type Heaven was bought in South Korea for about ₩165,000
Could have got better prices for the FC660C and RF104U by shopping around a bit more, but I had the wife in tow and her patience with all the electronics stores was starting to wear thin
Found Kakaku (
http://kakaku.com/) quite useful for Japanese shopping
