Nope....
I don't know too much about their new products - I got to bone up on them...I am going to carry the K1100+
Don't get too fancy with what you use....
I don't know - looks like it's still called the 5000 - K5000, K1100 - The K1100+ is a good product.
Their product line is mature so they are trying to grow sales by introducing more specialized products...
