You will understand later in you guitar playing experience, what is good from bad. It is best to not get something cheap, but to get something in the mid level-high level. A good mid level guitar is a Epiphone Les Paul. (Pretty much a cheaper, more affordable version of the Gibson models. It is also made by Gibson.)

for your first guitar you shouldn't get anything too expensive try to stick to the 500 to 650 range because you wont really get a feel for what kinda things you like in a guitar untill after you have played and had one for a while.
For an electric i started with a epiphone sg back a good 8 or 9 years ago when i started. but i have upgraded since than i use a gibson ES-335 with 57 classic pickups for my main guitar than i got a gibson les paul studio with P90's and i mainly been working with vox ac 30's for amps but recently got a pretty good marshal jcm 900.
and the es335 is a freaking amazing instrument
I can definitely vouch for Epiphones, since I own one. I love my Epiphone and it's taken alot of abuse over the years.
