I found the compact rothenberger used for 1700, but it doesn't come with the larger dies/head. Wished I had a threader for the last project I did, but...
What size pipe are you needing to thread? I do well with my Collins 22A Thread-O-Matic. Does up to 2", has two dies heads for threading up to 2". I use the snap-o-matic dies heads. I like the Collins better the Ridgid 300. I leave it in the shop and do prefab with it. Can be moved if needed if I'm doing a lot of threading. I also use the Ridgid 700, never comes off the van. For light threading it is hard to beat. I also have a ton of Ridgid manual threaders. I also have a Ridgid 65R receding threader, I use it a lot on 1.25-2" pipe if I have just a few cuts. The 700 generates too much torque I don't thread with it over 1" much. I prefer the Collins 22a for that or if just a couple cuts the 65R.
