I will have another batch coming that is only Duals. The Quads will take another 1-2 weeks but are a limited amount for the RDF discount. I have a waiting list for systems,but most of them are for Quads. I will send out a notification of Dual arrivals,and the waiting list will be first filled with dual orders, then the rest here. There will be a new code for the wait list. Thanks for your patience ! TMG If your on the wait list already,please specify which system you wanted. Several did not request which system.
