Often, cheaper doesn't mean worse. In attys, yes, with ST the quality can be a bit rougher but with these, not sure that you can go wrong. if ever you need to clean off some little burs, with a toothbrush or steal-wool you can easily do it.
Apparently I was very unhappy with a 22mm black SXK Lite. Probably because of the paint, but there was a little gap between the tank sections, and it didn't miss some leaking. Much less, but still the same issue with the 24mm ones. Just a tiny seeping but it's annoying. The plain SS ones are good but I far preferred to them some 10$ clones in both size I bought from here. They are flawless, hopefully - as i bought them nearly a year ago - the quality hasn't changed.
