Let My Fingers Play

I've been thinking about purchasing a used piano. The only problem is we really don't have a place by a wall that doesn't have something against it already, whether it be chairs, furniture, guitars, banjos or spinning wheels! I used to take lessons a long time ago and have been toying with the idea of a piano for ages. I was looking around on the web to get an idea of used piano prices and I came across this Piano Chords Blog which I thought was pretty nifty, especially in this house of musicians. It's a good site that the kids and Tom can use as some of the info is the same for any instrument. Music theory is music theory right? Now I need to find a suitable piano and the place to put it!
