This baby was re-capped before I traded to get it, but the friend who did the job does great work and the radio plays fine. I willingly traded a decent and desirable shirt-pocket radio for this 7S-P1 because I like the early Sanyos, consider the first two-band radios to have a certain historical significance, and consider this is a rare model. I've only seen one other sample to date, and that one had loads of chips and cracks in the hard plastic cabinet.
