I'm a guitarist with about four years of experience but I'm a novice. I want to take piano lessons at my local music shop. My question is what's an affordable beginner keyboard? The reason I'm picking a keyboard is its versatility, its cost effectiveness (is imagine its cheaper than a piano) and easy transportation. Any input would be great. I'm doing this because I suck at reading music and I want to go to music school or make music my career. I've taught myself almost everything I know except for one semester of guitar class in high school and I know I need more guidance.

Yamaha do everything i have learned over the years.

It is a Casio 88 key digital piano (not keyboard), the difference is, is that the only sounds it has are piano sounds, not a bunch of stupid tap tempo songs, horrible horn effects, or anything unnecesarry. It is a no frills piano that you can carry around, I have played that particular one, and it sounds quite nice actually.
