In Australia the 'above or below the line' voting system is used for the upper house (senate), which is state-based representation (and you can only select a single party, or number 40+ boxes below the line). For the lower house, we have optional preferential voting. So you number from 1 to something, and stop when you want. Then a slightly complex counting system occurs where votes for least-voted candidates are redistributed to the next preference, and repeated until you get a result. The upper house voting system does have some issues though. Most people consider voting below the line complex, and you can only mark one party above the line. Then independent senators only appear below the line, since they are in no party (which has caused an independent senator to make a party, just to appear above the line).
