Are you sure they don't have them in 40cm? I actually got some cheapy ones on eBay, probably same as Origin-8 quality, but I like them! When still figuring out what handlebars you like best, it doesn't make sense to drop a ton of money, so definitely check out eBay or a local bike shop's used bin. I used to have 42cm ones but they felt wide to me. It's weird cause 2cm seems like it'd be a negligible difference but I definitely feel it. Some people like 38cm but if it's too narrow you might not have as much control.
