I'm partial to the Spartan 300 with 100ft of the .55 cable. I feel like it hits the sweet spot of power and weight, and I was able to clear 85-90% of the clogs I came across when I ran that machine.
I had all the toys for it too: spear, bulb, 1.5 through 4 in C cutters, 3.5 in pear cutter, 3 in spiral saw, and this 4 lobed modified spear head that would blast grease stoppages into oblivion.
I usually started with the 2 in C, unless I suspected roots or a collapsed line. Roots got the pear cutter or spiral, degraded pipes got the spear. I always ran the camera afterwards if possible.
