I'll go through my notes later for a summary. All manner of excellent, marginal, and downright bizarre phone gear turns up on eBay. As with anything else, some is wildly overpriced and some starts out as a bargain, and may not end up that way. Caveat emptor, double for eBay. The Panasonic stuff seems to be the friendliest and provices the most bang for the buck, but this is a hugely subjective topic. Best thing I can tell you before I run out the door is to check out the newsgroups comp.dcom.telecom and comp.dcom.telecom.tech on Google Groups. The "home pbx" thread has come up many times, and there's a lot of good info archived there. --Steve.
