I paid $40 at Frys.  Great product for the money.  I have a Treo 750.  My wife has an iPhone 3G.  Both *automatically* reconnect to this thing reliably (and we also have bluetooth speakerphones in our cars).  Hard to believe.  There are a few things I'm not so sure of.  First, I don't think there's a way to tell which cell phone is ringing the home phone system - distinctive ring for Cell 1 vs Cell 2 would be great.  Also, I don't think name information is passed from either phone, although the phone number is.  Last, it would be great if you could specify how many times to ring the 'home phone' system -- my wife is often in-and-out of the house and absolutely hates her cell bound messages ending up on the home phone system; instead, if you could specify, only ring the home phone three times, then our answering machine wouldn't pick up the cell calls.  It also doesn't let you turn OFF automatic reconnect for one of the cell phones -- that would help for my wife -- as she'd prefer to just turn on the connection when she knows she'll be in the house all day.
