Yes for sure, I need to upgrade my system at some point. Another one I've used is a ziplock bag partly filled with water. I don't love the idea of plastic in fermentation, but it has worked in a pinch.
I wish that worked for me, I've found there are folds in the bag that seem to be good starting points for mold/infection. Unfortunately I'm not certain what in my process caused this, after a few tests I decided it wasn't for me.
Look at e-jen containers, they're for kimchi normally but I use them for fermenting tons of things. They're great.
