Hi Enkidu,
Nobbie's counsel is right on and applies to all would-be individual sellers of notebooks. Remember that you have to throw out the price you paid. You can only consider the price for which
Dell is selling your machine.
In your specific case, there's good news. Dell still sells a 5100 with your notebook's particular stats (with the exception of the CPU, which is now a P4 2.8) for over 1000 USD/1400 Can. In the U.S., the lowest-priced P4s, mainly
HP notebooks, can be had for 800-900 USD. And used but respectable P4s on Ebay, which usually has the best prices, don't seem to go for less than 700 USD. There are tons of used and OLD (2-4 years) PIII Dells and IBMs that go for at least 600 USD on Ebay. And they have just 30-day warranties! And worthless batteries.
Your comp is well-equipped, so you should pump the key features, the things people really want in a notebook: the 15.1-inch screen (big selling point), the combo drive, the dedicated video card, and the good-sized HD (not 30 or 20). Also make sure to let people know that you have a 5100, and not an 1100. That's important info for people who like Dells. In the U.S., I think you can get at least 600 USD/800 Canadian on Ebay. The ceiling's probably 800 USD/1000 Canadian (again, in the U.S. only).
I may be wrong, and correct me if I am, but I believe Canadian prices vis-a-vis notebooks are higher than those of the U.S. (even excluding the HST/TVH). So if you're selling locally, you should be able to get more money there in NB/Canada than in the U.S (also good news that you don't live in a big market, like
GTA, Montreal, or Van - less competitive prices).
One more piece of advice, rather than say that you bought your machine in 6/2003, you should say that it's 8 months old. It sounds better; what do you think about that? Would it sound better to you, if you were a buyer?
Let me know your thoughts.
