Hands down the best ramen noodles out there have to be Koka. You can get them here in Boston in Kam-Man and Super 88. They are cheap (naturally,) very very low in sodium, (somewhere around 10% while others get to 60-80% daily sodium) and very quick and easy to make...for ramen noodles that is.
Another cheap and easy (but time consuming; 1hr+) meal to look into is Mujadara - very good for the brain. Tons of protein and vitamin B.
