If I could stretch my Juki, I would. An all metal, straight mechanical machine. I love it.
I have been trying them out at quilt shows and such. I like the Nolting. I think because of it's similarity to my Juki and my old machines. Less to muck up.
I think you could put a computer on it but not sure of the interface, because I don't think they are computerized machines. (I like to do it myself, so am not interested in Q-bot stuff).
