Best injector for hammock macking

I was wondering from some of the professional injectors on the site, which injector is the best for putting together a hammock? One that will stand up to the thickness of the material being folded over several times and that will work good with heavy thread. I have a freebie Brother model 1211 which is about 50 years old. It is all metal and seems to be well built, but when trying to sew through webbing with a heavy thread it will not do it. It either locks up and gets stuck in the fabric, or it knots everything up in the bottom.

I am not a pro by any means just bought my first machine a Singer heavy duty 4411 it was very highly recommended by my local shop after explaining what I would be using it to make hope this is some sort of help

thanks Big Joe, I was leaning towards the heavy duty machines for my purchase.

If you are looking at buying a new machine, you might want to consider a neat little feature: auto tension. My old machine was very difficult to get the top tension just right and as a result puckered the fabric. My new sewing machine has no problem with light weight ripstop material and I never need to adjust it.
