@Cruiser Exactly! lurve
I had a keyboard and have had one (two, really) since I started piano. One day, when I went to play an acoustic, it was sooooo different. My hands glided and felt so much less choppy than they did on my keyboard, a Yamaha P-85. Therefore, I suggest getting an upright piano. Watch out tho—If you want a decent piano, pay the price. It may cost more to tune one that to buy one in need of tuning. I myself honestly don’t care if a piano is out of tune. at least somewhat in tune, unlike my 112-year-old piano at my summer office. I do care if all the keys actually work, though, but as long as I can scrap out some sort of “melody”, I’m satisfied. Steinway is a nice brand. There’s a store right near the Boston Common where I go all the time to play on a real piano. They’re really nice. If you’re on Craigslist, perhaps consider going to look at the piano before actually buying it if you can.
sorry if this response is too late; I figured better late than never.
