Let me throw in my 2-cents.
I started with the MH871 32" and at some point, got the SC (my MH had the USB port break when I tripped on the cable -- the replacement board was cheap and simple to install, but in the process of ordering the part from USCUTTER, I decided to spring for the SC and keep the repaired MH as a backup)
A while later, I sold my entire sign shop, and the SC went bye-bye as part of the deal.
After more than a year, I re-opened in another spot, and placed the MH into use again.
Heck, I did a big job today that was worth 1/2 the entire value of the machine!
That MH is a workhorse. To this day, it serves me well, and I have had no problems in cutting all sorts of relatively minature stuff, as well as long vinyl runs, up to 20' or so. Put it together with an older laptop with a serial port, cut with SignBlazer or VM, and go.
