TRS-80 Model 1 (Tandy, 1977). Estimated units sold: hundreds of thousands; original price: $599; current market value: $25 to $250
The TRS-80 or Trash-80 was sold at Tandy's Radio Shack stores. It was probably the first computer American consumers encountered at their local shopping mall. Ugly and spartan but extremely useful, it spawned an array of add-ons, spinoffs, and successors that made Radio Shack the world's leading computer retailer for a period of time. Vintage examples don't cost a fortune.
