Pails for Scales have a few, I think Amazing Amazon have a few too. Probably be careful though- you don't want to be known as a tyre kicker

And monitors aren't exactly for beginners-
probably best to do some long hard research before delving into breeding.
- Start by researching everything,
- then set up an enclosure-
- then find a small breed to start with-
- only buy one of them and preferably a baby so you can learn how babies behave and observe the behaviours and the growing process
- ...then watch, read and learn some more...
- after a year or two of ensuring you are serious about it,
- and have been bitten,
- scratched,
- had poo up to your eyeballs,
- dealt with the cleaning,
- feeding
- and nappy changing,
- then and ONLY then will it be time to breed.
Do it intelligently, and you (and your monitor) will be much happier and healthier because of it.
Good luck
