Well then it's sad that i don't have any. And since i can't afford to get a teacher could you maybe reccomend some books or online tutorials that you know are better than others?
As mentioned the Alfred series can be good as is Bastein. You can read along in the Bastein studies what would be the teachers instructions better than in say the John Thompson series, where the instructions are more teacher specific. If you do an online search on each topic you then can learn a bit more in one or two of many tutorials that usually will be posted online, either in Youtube fashion or in blogs. There are several good sources online worth watching or reading, though some are pay sites to get to the best information. I know today people expect to find most things for free but sometimes a small donation isn't such a bad thing.
Saying one can't afford a teacher and really not being able to afford a teacher can be two different things. Sometimes it's a matter of how dedicated one is to piano and willingness to give something else up to be able to afford the teacher. Over the next year you might want to assess where you stand in that regard. Sometimes there just comes a point where piano means more than something else and you are stuck in self teaching and just know a teacher could dig you out of the rut. And then miraculously the means is found. Also sometimes, the mantra " I can't afford a teacher" is just automatically cried out with beginner students, then they discover they can't afford to not have one as they are just wasting time on their own ! You will assess all of that in due time. Eventually it won't have to be explained to you as you come to your own conclusions.Your piano is what you have, it will do for now. In time you want something with a more filled out keyboard and fully weighted keys if not an acoustic. Acoustics are slowly falling by the wayside though, digital technology is getting closer every year.
