You don't need to get rid of the torque master. It will still work with a LM3800.
The largest cost is machining the tear-shaped profile into the hub. It is definitely cheaper than throwing out a good torque master tube and replacing it with a bulky torsion assembly.
I machined the profile into the hubs. Didn't do anything in the middle of the tube. The hub can slide the length of the bar and can be mounted on either side.

I originally had 2 of the small sprockets on the system but found that since it doesn't have the Ø3" - 4" cable drums, the door would crawl up (30+ seconds one way on my 9'W x 8' H). The larger sprocket reduced it to a more realistic value.

I thought the link was working. I will double check. Do a You-Tube search (Liftmaster 3800 on Wayne Dalton Torque tube)

Conversion kit for Torquemaster system to Liftmaster 3800
Thought I would throw this up here and get some comments (positive or negative is fine)
I generated a kit a while back that allowed me to mount my Liftmaster 3800's onto my Wayne Dalton Torque master system.
I liked the fact that the...
I made a kit that allows you to use your existing TorqueMaster torsion tube that adapts to a standard bar which can be mounted to the opener. Here is a link to my video. Works slick on my 3 Liftmaster 3800's and was cheaper than throwing out and replacing with a standard torsion assembly.
