Umm... well if your going to have a piano lesseons you at least need a keyboard to practise on. In the first few lessons I learnt stuff like hand position and simple stuff like the short and easy version of "ode to joy" and "raining cats and dogs (all you have to do is the notes like this= cdcdcdcdcdcd!)". Unfortunately I don't know prices... my piano i've got is acctually my landlady's! But i've got a mini organ and a keyboard and and other instuments like the recorder to practise the notes on!

Anyway if you decide to take the lessons good luck and have fun!
