about a month ago I broke a key on my wk 1800, the part with shipping for an octave was only 10 bucks, however hehe I fixed with super glue temporarily (I thought) and moved the broken key from the middle c area to the top of the keyboard which is used less often.. anyways so far the super glue is holding and I havent needed to use the replacement part yet... ps. there were a million screws to take off kinda of a pain..
