While I'm not a fan of these, I do understand it's one of your dream snakes and I'm really happy for you, it is super exciting to get something you've wanted for so long!
Don is a great guy, I've bought corns from him in the past.
Something cheap and easy and what i did for baby corns - get a toilet paper core, cut it in half lengthwise. Ta-da, instant tiny hide that is free and easily disposable when soiled.
They'll outgrow tiny hides pretty fast so I wouldn't waste your money on buying some. Also for an easy small water bowl, I use ramekins.
Good luck with your new little one!
