i agree with sifu... in my opinion it's way better to buy a cheap electric and a cheap amp than to try to make every step from nylon to steel to electric... i've never considered nylon stringed guitars as steps in the same path of the electric, and steel stringed acoustics are half-electrics just if you play them in the wrong way... acoustic guitar is a completely different league in my opinion. you can later discover the pleasure of acoustic instruments, but if you can't really play the will be extremely frustrating to start with.
personally i began to play "seriously" (ehm...) when i bought my first electric, because it was what i was long dreaming to play, and everything else was just surrogate.
if you want to practice in your room, have fun, playing on your favourite records and learn how to use the tonal possibilities of an e-guitar you should buy some modeling equipment (personally i hate it but v-amp is very, VERY affordable, and you could even find it used) and care nothing about pedals, amps and various technical tricks but still begin to learn something about the way the sound is modulated, distorted and amplified in a chain of gear... this will be very useful if you want to continue playing.
a cheap amp can let you rehearse with your friends, but this will come later anyway... and cheap (very cheap) amps can be quite frustrating because you will hardly get a sound you'll like, and you will end thinking that's all because of your awful playing!
so... i'd go for a cheap ibanez (best value) and a cheap amp modeller. now you can...
