Trick Tools makes benders? I thought they just sold them. In any event, is there a reason you can't get the dies you need/want for your current bender? Most of the JD/Pro-Tools/JMR benders will go down to 1/2" diameter tubing and the smaller dies really don't cost much compared to the big ones. How small do you want to go?
For fluid type tubing (1/4" to 5/8"), you could use something like a hand held roller-die bender or a stationary unit like
this. Conduit benders work but are limited in terms of bend radius selection. Depending on the wall thickness, you'll also tend to get more deformation of the tubing at the bend than you would with a die-follower type of setup.
