Some readers posted recent comments about the Kchibo KK-S500, which recently appeared on eBay with a surprisingly high price. This is the first Kchibo radio (to my knowledge) with sync detect, which may explain the high price. It has a very similar appearance to the Sangean PT-80, although the screens on these two radios have different appearances.
I have a hard time imagining that the KK-S500 could be a lot more valuable than the Degen 1103. Take a look at the KK-S500 auctions on eBay and note the absence of phrases like "from one of the best radio factories in China" and "from the makers of the famous ###### model".
