I prefer Sled style drum machines vs the upright style drum. Sled machine is more stable, cable feeds in and out easier. I like the open reels also so I can see how much cable I got left and to allow cable to dry and not stink up the van as bad. I also like sectional machines for their versatility, but they are more labor intensive to use.
My go to machines are the Gorlitz 68HD and the Ridgid K60 if the blockage is in the building sewer.
