My very first keyboard, GEM WX2 (mid eighties?) but returned it as soon as I found out it was filled with lots of bugs... My real adventure started with Technics KN2000.

KN2000, KN3000, KN5000, Solton X1, Ketron SD1, G70 (bad choice), PA1X, PA1Xpro (just not my 'type'), Tyros1 (great).... and waiting for my Tyros2 (Probably the best)
