Re: "I saw that you got a zenith Z170, well, i've got a Zenith Z171, and i want to sell it, do you know what is the price for this kind of device?" The Zenith 170 is a generic name for the 171 ... two different names for the same computer. These show up on E-Bay fairly often, in various conditions. They don't go for very much, I'd say that $19 or so is a typical price, sometimes less, sometimes a bit more. The shipping cost will often exceed the actual selling price. Do an E-Bay search on complete auctions, although many won't list the model number (either 170 or 172) in the auction title.
