I use Petrus. Very intuitive, and not many algorithms to learn. Petrus gives me times like 30 seconds, and i learned it only about a month ago!
You could also learn the roux method. Also very intuitive. Still not many algorithms to learn. I learned it a few days ago and it's given me sub-minute times!
Here's the link for Petrus: Rubik's Cube Solution
Here's the link for Roux: The Roux Method
Good luck and happy cubing!
