Thanks, Kriston! The keyboards I mentioned both have a pedal (to purchase). LOL about the sound effects. DS has a toy cat "piano" (since age 2). He loves to hear it mew songs - ha!:) These days you can get a piano for practically nothing though, as long as you get it out of the person's home. I wouldn't buy a pinao new. I didn't thik about taking it on trips though.
More thoughts are welcome. He doesn't have lessons again for 2 weeks; but he is supposed to be practicing now. So I need to get something this week.
