fp, that's weird. I've called them a few times in the last few days, and was told they were having a "porosity problem" with the caps and it would be WEEKS before they got the right ones in. I called today and it turns out they just don't have the thermowells in stock, so the one that are packaged together aren't available, the caps alone are. Bad info on the phone. Anyway, if you happened to have one with a thermowell I'd be glad to buy it. If not, I'll wait a week I guess...thanks for all your great info!
