I still have two Dreamcast systems and one is always hooked up to a Sony Trinitron. In the top 3 consoles of all time in my opinion. Highly recommended to anyone today who does not own one.
This i can recommend at least used a dc doesn't cost to much but for the games it does depend on the title.For anyone that doesn't want to collect for the console there are optical drive emulators and even a hdmi mod for a better picture.
