If you want to wait for the "production" run, I figure it'll be about a month before I have full guns ready to ship.
If you'd prefer, you're welcome to E-mail me a "wish list" of the components you'd prefer and I'll work up a finished cost for you. In that case I'd need a down payment and figure about two weeks once I have the annoed bodies (or two to five weeks additional for custom-order anno.)
