Yup, I'm pretty set too. I might run out in 20 years or so. Probably need to stock up on just a couple more cases.
ETA: If you've considered purchasing bulk bulbs from Amazon because of the links at AoSHQ or Instapundit, purchase them knowing this: The reviews from people claiming that the bulbs do not seem to have been quality control checked are TRUE. I purchased several cases of 24 Sylvania bulbs - 100, 60, & 40 watt. Sylvania is normally a reliable brand. I don't know if it's the way Amazon packages them for shipment (seems a bit unprotected to me), or if these are factory seconds, or if they are generic bulbs with the Sylvania name on them, or what. But I went through each case and inspected each bulb because of the reviews I read, and in each case of 24, there were one or two bulbs that had the filament disconnected from one of the pole wires. No fix for that, they're junk. So a case of 24 bulbs was really a case of 22 or 23.
As a consumer, I was left with the choice of going through the hassle and time of returning several cases of bulbs and making sure I got credit, or eating the loss, so I ate the loss. The end result is that my value per bulb probably ended up not being a net gain over just going to the store and buying them there.
