long time no see.
Then again, some still may know me around here.I have an unused 73 Key frame from my old M3 if anyone has use for it. Make me a reasonable offer. Located in Germany. Original packaging still available ( I think, must check, but pretty sure.) We can talk about it via skype as well if you wish so.
I checked them out, but then never used them due to my dislike of unweighted keys. They were wrapped up again literally after 2 days testing.
