Konica-Minolta C6000 vs C1060

Hi guys.

I've got intresting offer from our Konica-Minolta salesman.
He told me, that they can replace my current C6000 with newer C1060 model for slightly higher monthly fee.

Is it worth to do such replacement ?
What are advantages/disadvantages between C6000 and C1060 ?

As i found - C1060 has sheet registration mechanism, so there should be less problems with image registration comparing to C6000.

Any comments are welcome.
Anyway, if i decide to go into this business i will need to disassemble part of wall in my shop to move it out - as i did to put it in 4 years ago
