[deleted] well, for belts it is really important that they have a good fit.
There are some good steel cages from china, but no good cheap belts.
I'd take a look at Mysteel, they have a belt, for transvestides and I guess Neosteel also has one.
I have a Mysteel untouchable with tube, it also has a shape where you can't explicitely see the male genitals or the tube. Or take the Latwoski, it's similar to the untouchable but with some extras that make urination easier. The cocoon is a chine belt that also covers the genitals
