Thanks to everyone who tried to help me find a Dreamcast.
It seems that there are no new consoles left anywhere on the net for less than $150. There are a few used ones for $70 and up. I bought the CompUSA demo model, but unfortunately it doesn't work. I still definitely want a Dreamcast, though.
Good deals:
CompUSA - many Dreamcast items are marked down to $5, but the price tags are still higher. If you see something you like, ask for a price check. You may be suprised.
Best Buy - $15 new controllers, $10 VMUs, and some other cool cheap stuff. Check them out. Some of their prices are also lower than marked.
Circuit City - was having a $35 DC blowout, but the consoles dissappeared REALLY quickly. Too bad. They still have some cheap accessories.
I went to Funcoland.com (thanks to whoever suggested that), but they don't have the Dreamcast Console. They have some really cheap accessories, though.
Anyone know where I can get one?
