I have some of those valves on order at the moment and just prior to Thanksgiving I heard from Rich at Reptile Basics that he was having trouble with the supplier being late on shipping them. Last I heard (Tuesday before Thanksgiving) was that he should have them in and be shipping them out on Monday, November 28th, barring any issues. I have yet to get them to use them but have a rack built that they'll be installed on. Anyway, thought I'd let you know about the delay if you need them in a hurry.
