Welcome. GLAD TO SEE YOU HAVE FOUND THE WORLD'S GREATEST ENTERTAINMENT SYSTEM! Good question, although I've read this thread many times, this always a good thread. Head over to the sales/trade forum many people have extras to sell, trade. I will say don't expect people to just throw you deals for no reason i.e.keep this to a minimum, sounds too much like "I'm only here to take advantage of the community" I've only been here a couple of month's and posts like that generally garner a lot of hate if they become persistant->
btw i wouldn't mind if anyone would be willing to sell me any of your duplicates of any turbo game- i don't have any Anyways
after a few weeks here, you'll understand why some people are protective of the community, it's pretty awesome here.
That being said FiftyQuid has a system and some cheaper games up for sale at the moment, You may want to try there, But be warned the Wii is the much much much cheaper way to go.
To answer the orginal question: BACK in 90 my dad got a used boxed turbo with games and all sort of extras for $75. I then experienced my first video game BONK's Adventure. The rest is history, played those same few games over and over and over. Until recently I got back into it, found my way here, and love every minute of talking about the system.
