I rather prefer my Lineman's Testset vs a Beige Box ...

Simple to do though, just snag a couple alligator clips, some cabling, and an old phone, then snag some solder and a soldering iron and build yourself something fun!

Plenty of ways to make, and improve upon it, depends on how much time/money you want to put into it lol
