Manual machines like this on eBay 331261673650 are good enough. You can get ones with an pneumatic ram for bead breaking but that's not usually the hard bit.

I did make my own bead breaker out of bits of scrap in about 20 minutes but don't use it anymore (converted it into a shock/spring press!) The bubble balancers are also sufficient for landy work - and speed (or lack of)
