I have a modded Dreamcast free to a good home if anyone wants it and lives in Melbourne or Sydney. (I've found emulation easier for me these days, as I try to simplify my physical setup).
How is it modded? I recall that certain models, identified by some number on the bottom of the console, allowed burned discs to be played. What extra can you do with a modded system?
That said, look them up on ebay, you'd be able to sell it for a few hundred within a week early.
Also, if you every want to use light gun games on a CRT, they don't work easily with emulation.
