Talk about a blast from the past!
I loved these Sony ereaders back in the day, especially this cute red version; sold a few in my store and still have a black PRS-350 in my collection.
Sony PRS-300RC Digital Reader Pocket Edition - Rose
$48.10 with free shipping from VIPOUTLET, 3rd party seller on Newegg.
Does not indicate whether new or refurb; battery life may be poor (IMHO).
I have bought from VIPOUTLET before, they are reputable and have paid refunds for defective returned items and non-received items.
