Quickload is out of production, and the last relics are near expiration date. There is no point in getting into it if you don't already own a holder.
That means cut film. Try to buy a set of identical holders - a mix of holders with different feel can drive you nuts (or even cause catastrophic failures) when you attempt to load them in a dark bag. I'd stick to Fidelity Elite or Lisco Regal (all made by the same maker these days - there is not really any choice where new sheet film holders are concerned), as these are all over the place and affordable. There are better, more fancy used holders (e.g. Linhof branded), but be prepared to spend lots of either time or money to get hold of a working kit - bargains are rare and tend to be solitary ones.
Another option (if you were considering Quickloads for their small volume) are Grafmatics - automatic six-sheet holders. Being a metal construction, they are not much lighter than the three wood/plastics double sided holders each would replace, but they are barely bigger than a single one of them, and they allow you to fire six shots faster than you can wind on 120 film. But research them before you buy any, so that you can spot the issues (notably bent/missing septums) they may have.
