Apologies in advance if it's against the "rules" to post things like this here...
I have a Sonoline B doppler to sell. I bought it for $60 on ebay and used it for maybe 4 weeks before I could feel baby kick and didn't need it anymore. Needless to say, it is in great condition, practically brand-new, and I have a bottle of gel I'll include too.
$40 OBO - email me if you're interested: julielcarter at gmail dot com.
