But I'm out of *all of them*. Somebody at Intel corp cleaned out my stock recently, apparently they couldn't wait for replacements from mfr.
More are on order but they all have a long lead time of about 6 weeks.
Edit: Just got confirmation from MicroPlastics -- order for plastics is due to ship on Oct 11th.
