i have just tried sellig my sd1+ and the best offer was $1100(AUS) about $975 US...i bought this for $3100AUS about 9 weeks ago...just goes to show that you can't sell em, so once you buy a ketron its with you forever (or a very long time anyway)...i think my only course of action will be to try and get some info from ketron about installing an alternate keybed, maybe even a weighted one, although i dont expect much joy there either...its one of the reasons i was looking at the used g1000,because i believe it has the same keybed as the va76 and i owned one of those and it was excellent....
