I don't think knee lifts can be retrofitted?? But, in this case I'm sure if that's even possible, it would cost more than the machine:> It cost me $95 for just the basic service on my Janome and if they have to replace anything then it will be more. So, I don't think $250 is unreasonable for this machine. My first machine was a Viking. I only upgraded to the Janome for the embroidery features. I was hoping to find another Janome as my back-up so I could use the same feet, but if this one has all the feet and cards I'd use....wahoo! I go see it tomorrow, so fingers crossed:>
