Squeak, I agree. A few thousand is too much to gamble, but $1000 or so, imo, is in the range to check out and dump. I believe Harold is selling his E60 for that. Who could go wrong with that purchase?

Harold, I agree with you too. It takes a long time to assess a keyboard; it's potential, ease of use, pitfalls, etc. I believe this is a must stepping stone to end up with what you're looking for. Can't do that without spending lots of time.
