Greenlee 250 steel with a leader, Greenlee 150 nylon, no leader. I admit Ideal makes the best non-metallic fishtapes, but the day I needed one, the greenlee was on the shelf so that was what I bought and haven't been totally disappointed. Gardener-Bender = Junk in my opinion, for the most part. Got a couple rusty old GB's floating around the shop that I avoid like the plague- they are almost impossible to wind up after using them, and that "handbrake".. why, GB, why??
My true favorite is an 8' scrap of someone's old broken tape.. that thing has gotten me out of many scrapes and saved me the hassle of having to get out a full sized tape to get the little jobs done
