I've been looking at Keyboard prices:
The Bontempi GT740 only 40 midi-size keys
you saw at elc - £69.99
same one at Play.com is £65.44 + £3 delivery
same one at Tesco is £48.77 free delivery
__
There are bigger Bontempi ones, obviously get more expensive as get larger/more keys/more features.
=====================================
The Yamaha YPT 220 has 61 full size keys, and instead of batteries comes with a mains adaptor, and many more features than Bontempi.
Best price I found so far:
Amazon £69.99
So that is a BIGGER and BETTER Yamaha (about the best make there is)
for the SAME price Early Learning Centre were charging for the little 'toy' Bontempi!
Now, I don't want to bully you in directions you might not want to go, but please do plenty of research and compare prices before you commit to anything, or you risk wasting money.
