Hi all,

I was wondering where people bought Pt/Ir apertures for the FEG FEI instruments. We just got a rash of terrible apertures from Ted Pella. Pella is working on the issue, but I wondered what other vendors people used. FEI sells them, but they are very expensive compared to Pella -- maybe it's a case of you get what you pay for.
