The 302 you referenced, sebbel is not your run-of-the-mill 302, straight from the flea market. It looks like the seller spent a lot of time making it a beautiful yet functioning collector piece. Perhaps for the person looking for just one perfect phone for their home or office, it's well worth the money. Looks like a top-notch job.
Disclaimer......I do not know the seller but have seen his/her work in the past. Looks first-rate. Even the dial card is original.
