I just have the basic version 16 not the plus as it was cheaper and I don't need the extra features.
An older version of Magix Movie Edit 12 is as low priced as $6 from places like Amazon MarketPlace (qualifies for super saver free shipping).
Over at VideoHelp I noted a couple more Free editors that seem to be able to cut/trim without re-encoding - ie: lossless - in addition to AviDemux
and MPEG StreamClip
