To be able to multibox you will have to be able to pay for two or more (depending on how many you want to box) accounts. Software wise there is keyclone which is cheap and very goodlike, I myself use AutoHotkey which is free and does the job although it takes a lot more to setup. If you plan to go the hardware route then of course you will need to pay for the new equipment. In short yes you do need to pay to multibox but once everything is setup it is relatively inexpensive to run (relatively is... well relative to your current financial situation) Hope this helps.
