Gutbucket has a good memory; I did indeed buy page's 4015s.
I am a reticent gear fluffer, but, I have to say, I love them so far. They were a little bit of a "holy grail" mic for me; I have wanted them since the first time I heard samples. Lee and Moke's assessments (natural, open, smooth off-axis, good bass response, with some directionality) are pretty much spot on. I haven't had the opportunity to use them in my preferred scenario (jazz in small rooms), but they have performed well in venues ranging from bar to medium (~ 300) and large (~ 1500) sized clubs. I have posted several shows to LMA. I can't wait to record some jazz with them; hopefully, that will happen in the near future (some dates on the radar)...
As for the 4018, there are a number of recordings on bt.etree. Search scottsch. A lot of Phish, but some other stuff as well. There is another guy who has posted a few, but I am blocking on the name. [EDIT: mgd1016 is the other with some 4018 sources on tree.]
