S.B.
Please look online and at Home Shopping Network or QVC. I bought my kids one and it's awesome. Can't remember with channel I got it on though.
I have a piano, but it's not easily dragged around from room to room and this one had choices of adding drum beats, etc. It wasn't very expensive and it was on value pay meaning you just paid it off in 3 or 4 interest free payments.
It's a Casio and really cool. You can make it sound like a harpsichord, an organ, you can record things you played. I'm a single mom and it was very affordable and brand new. Came with all the instructions and music booklets. It was a Christmas present one year and my kids love it.
Check the home shopping channels. At least that way you know it will come with everything you need. If I remember, the stand for it was sold seperately, but still very affordable.
They can have it shipped to you in a week...check it out!
Do you have a music store around you that sells used things? That's another place to look.
Best wishes!
