The model S200C and S100 cannot use the same display controller and the cable reel. Because S200C is an HD crawler. So for the proforma invoice of S200C and S100 will be two complete unit systems. Please kindly confirm and we will send the proforma invoice to you. For S300, it can work with the same display controller and the reel with S100. Please kindly kindly find the invoice attached (We reduced $1000 for S300 crawler) Also note that we issudeed this PI with our subsidiary bank account as our main bank account is currently on audit and wont be available for transaction until further notic Show More
