Dream casts cost a lot because they were hard to find when they first came out. But when the ps2 came out they were put away for the ps2. But i dont understand. The thing i just said was about 10 years ago which was when they did cost a lot. Now a days you can get them at almost any used game retail place (not gamestop >_>) for reletively cheap prices.

ill sell you mine for only 5000 dollars.

Dreamcasts are expensive because they are rare, and also very valuable.

I found mine in a Goodwill for $10. Now before I come off like too much of a pompous ass, the system didnt come with any controllers or games. All it had was the ac adapter and av cables so as of now its simply a paper weight that I can plug in.  But ultimately one must never underestimate the awesomeness of ones goodwill/salvation army/ thrift store.

Dreamcasts are cheap, found 'em for 50$ or less. 
 
A Sega Saturn's pushing it, those I've seen for 100-150.

I'll sell you mine. Then I can go and buy another one.

Because people like money and other people are willing to spend it for a Dreamcast.

I have about 6 dreamcasts at my work. We sell them fro like 34.99 with two controllers and a vmu. If you pay for than $50 for just the system you are getting ripped off.

I got one for £20.50 at Gamestation, with a controller, Shenmue, Toy Commander, Virtua Tennis and Sega Rally Championship.

That is an awesome deal! The highest ive ever seen one go for has been around $60 but that one was still in the box with all original documentation.
