Looks like you're still not quite getting it...
Three wire power does NOT require the phantom adapters. You can run the miniXLR terminated mics directly into a suitable 3 wire battery box or preamp. Not many people offer them but I believe Chris Church can make you one if you wish. The phantom adapters do nothing but add bulk, although if you've got them you might as well use them. There's nothing inherently bad about them (other than the bulk) but not worth seeking out IMO.
The price I quoted for the mics was from visiting SoundProfessionals website today. You can check yourself if you don't believe me.
I never said Chris' preamp cost 280, I quoted the 230 that his eBay store lists it at but also pointed out that he offers it for 180 (now apparently 140) in the Retail Space forum.
Edit: Also, there's nothing "inferior" about the "low sensitvity mod" offered by SP vs. the 4.7K mod invented by Chris Church. It's the same thing. One might not like the fact that they copied it (then again, it's not as if Chris patented it and I doubt he gets rich doing it for people, seems like he's doing you a favor by offering the mod at the price he does), but it performs exactly the same because it is the same. I'd suggest if someone is buying a new set of mics from SP they might as well have SP do it rather than wait for the mics to arrive from New Jeresey only to ship them off to Canada.
