Does anyone have any experience with this tester? Good/Bad experiences? I am about to stop the part time wiring and go full time. I was looking for a cheaper solution than the Fluke line of products. Remember I am just starting out so I need something inexpensive, but it needs to be robust. This unit seems like a pretty full featured product and also a very good price ($935) I am not asking for the world, just need something good to start with.
