If you're into electronics it's good as a second meter. I'm currently considering to buy one myself (but will probably go for a Brymen). I don't think it's good as the main meter for electronics as it lacks in some areas, e.g. current measurement.
My experience in used equipment in Japan is that they are quite abused, a lot of scratches, dirt, smell cigarette smoke, and so on. I try to avoid used if I can.
Have you checked Rakuten or Yahoo Auction? Best price of new Fluke 179 is about 34000yen (US$277). At Yahoo Actions there is one available with some kind of test leads, asking 14900yen (US$122).
