An important point that no one has brought up is warranty. This makes Microsizers (US version of TOMY BC-G) the best choice hands down. When your clone stops working the second time you run it, you can't really do much except say, "oh well, it was only $15." But if you have a problem with your Microsizer, you can go to microsizers.com, fill out a service request, and they will fix/replace it until you're content.
