For now, yes of course to buy a 110V would be a lot cheaper but not those days. Besides this is just a differece in electrical knowledge. As long as it's protected and fuse/breaker installed, ?I don't see a problem at all. For sure this is a user's decision, taking the risk or not is very depending on the confident level which could be simple backed by knowledge.
a fuse or breaker is not a solution to prevent an accident in this case.Using 220V this way,the appliance from China might still have power inside it even it's power swithed off. (depending on how the switch is designed to controll the circut).
