I want to try full chastity belt, but i don't have money for buy. I having plastic chastity cage copy of cb6000s and copy of holytrainer, but plastic cage special for small periods.
If you don't have the money to buy it, I would forego the idea. Don't let this "lifestyle" start to effect more important aspects of your life. If you are looking for something more serious, get a piercing and a cage that accommodates the piercing... I am sure it is cheaper.
Welcome to our community. I hope you find if helpful and enjoyable. Good luck with your search for workable solution to your chastity needs.
If buying it right now isn't an option, make it a long term goal. Investing in a good cage is worth it, but understandably can take some time.
