One very important thing that you should consider when choosing a guitar, is the type of music you will be playing. For example, if you play a lot of hard rock or heavy metal, you might want to get a guitar from Jackson, B.C. Rich, ESP or Ibanez. These brands make most of their guitars with thinner necks and lower action (strings lower to the guitar neck). Both of these features allow for faster and easier playing so these are good guitars to shred on. Another example is if you play a lot of blues you might want a Fender Telecaster or a Gibson Les Paul. These guitars are mad with smoother sounding pickup which are perfect for soft rock, blues and jazz. It is also very important the the guitar you choose has the right sort of sound for your preferred genre.
