YES... TM all the way since you ask.
Just depends on what you want though.
- height would be good in TM.
- TM is strong stuff. It's ABS. Get it 2mm if you want it like FX. But my 1.4mm is totally amazing and will last a long time I have no doubt!
- TM is a harder build than FX, but you can do it. And if you go TM "all the way" that would include a lid... right?
You can't get new FX armour anymore. You know that right? It's AM armor now. But yes, your price point guess is pretty good.
