I have only seen a 5000' reel once of cat5, in the early days of it. (Cheap import knock off stuff) And never more than a 1000 of 5E.
What TDR do you have? I think these are that coolest thing out there. I have a Psyber (m.s.) (Numeric), and the shop has a Megger (Graphic). Both are really usefull for troubleshooting all kinds of stuff. Especially if you sample VoP's of larger wire, like 14 - 2 in conduit or cable. Use it to find screws in cable, and on occasion hidden j-boxes, and splices with the graphic.
