After 13+ years of playing in chastity, the first one will not be right, it took me years to find one that worked for me. I'm smaller than 'average' and had all kinds of issues at first. My wife and I have ordered everything from custom sized cages to cheap one's on wish and Amazon. I recommend buying a couple cheap ones first and trying out to see what you like or works for you. Lots of situations call for different cages. I ended up finding a metal cage with a hinged ring that I customized for my full time wear. Then I ordered a 2nd one and did the same customizing to it so I could always stay locked up after my wife supervises my deep cleaning process.
