well..i bought a ds light...and its very good so far..the screen resolution is by far better than the original...the graphics seem to be improved by the sheer nice-ness of the screen....i love new super mario bros by the way!

Nintendo DS Light- 9.2/10

New Super Mario Bros- 9.6/10

overall i am very pleased with my purchase..if u have a ds and have ideas for my next game i should by..pleas leave a comment with your idea!
