Talkboy
Average original price: N/A
Potential earnings: $130
Boys also had their own version of the Dear Diary- the Talkboy. These gadgets became popular in the 90s mostly because of Kevin McCallister, who used them in Home Alone 2. We couldn’t find the original price for the Talkboy either. However, you can sell in on eBay for as much as $130. It’s difficult to find one of these gadgets these days, as everything has been replaced by modern technology.
