That looks like an '85ish Maruishi, so I'd say it is well worth the asking price.
The early Maru's I've seen are POC's - but the later Maruishi's are beautifully finished, with Tange frames, nice handling, and light weight.
They don't have the name recognition at all though, so they go for less dinero than the equivalent Miyata.
