OK folks, after discussing production costs with Carter, and in light of the apparent scarcity of the source mirror (I've had a lot of trouble getting a hold of very many at a reasonable cost), I've got to price the mirror and adapter combination at $199, which will include USPS priority mail shipping in the lower 48.
I am going to open up pre-orders at this point. Paypal can be sent to
agchoset@gmail.com, and as soon as the adapters are finished and sent to me, mirrors will start to ship. For a $5 discount, you can send a check or money order, PM me for mailing address.
