Sales advice

[jupiters_spot]

Twenty years ago I purchased some HP goodies for a collection that, since the arrival of my kids, has languished. I'm trying to thin my collection and wonder whether more active forum members can offer advice on how best to sell? I have the following:
- Two working and clean HP-21 calculators (Museum Link)
- HP-21 Owner's Handbook
- HP-21 Applications Book
- Locking "Security Cradle" for Woodstock-series calculators that comes with two keys, instruction sheet, and original box.
- 82026A charger (for use with Woodstock-series calculators) in original box
- [edited to add] Working HP-48S calculator with owner's manual [/edit]
I have bought and sold on eBay, Craigslist, and (back in the day) Usenet but I wonder whether those venues, or perhaps the Classified section of this forum would reach the widest audience of interested parties. Any advice from sellers?
