Biz - I saw a 5300cs go for $120 on eB the other day, with some software and extras. Wegener was selling 5300s for about $50 for a long time, they may still be. I would say a good condition 190 with a battery and power supply would go for between $30 to $60, generally. But that 5300 price may signal that these units are getting rarer and hence more prized.

I have seen a lot fewer 1400c models on eBay of late, too. Glad I did my buying when I did.
