ordering the microartwork crawler

I know that some in the forum have ordered Mischa (Cyana's) stunning Crawler from Microartwork.

I see the Crawler as a future aspirational project and want to order one as they are a limited run. Microartwork's site says they are still available and not to worry if it takes a bit to get the bill via paypal.

That said, I emailed a week ago and haven't heard back. I totally understand that few if any in this community can do this as a full time job and I hate to bother others unnecessarily. Any advice as to when I should be concerned something happened and follow-up? What kind of time frames did you have?

Thank you, Eric
