I use my mod'd 77HP tracer 2 for toning. I put in a barrel and soldered it to the pcb, added a jumper. easier for toning cable than trying to get the alligators to grab a fitting without scoring the center conductor or whatever. Also tones thru splitters, amps, rf modulators, etc.. which is good on apartments that arent tagged and you can't find the splitter. You can also locate where the line runs in the drywall (combined with TV-90 makes locating which painting the moron hung with the oversize nail in the wrong spot) and is much more compact than using a drop locator in that situation.
I have another multi-drop toner. Only does 4, but you don't have to throw any switches (other than on/off) and it seems to have lasted fairly well.
I don't use it that much in this system, was good in phoenix i could tone out the mta outlet, modem outlet, and main dvr locations in one trip in those 15 outlet mansions.
Brain hurts. Laptop crapped out on me. Vista repair wouldn't recognize a copy of itself on here so I had to reinstall. Vista is dumb and wipes the hard drive when you reinstall unlike prior versions. Lost a lot of CAD work and stuff. Depressed but glad I have my desktop as my file server/backup for the rest of the stuff.

Tools are fun.
