Ah Gees! why did you have to go and ask that question???
maybe this will be easier than I am thinking.... Which disc is it? is it one of the new Disc elites or Extremes? If so they are awful hard to beat. If it is one of the older Disc's then maybe it might be toss up - but remember new is new and used is used. Will you get to inspect this disc prior to buying?
On the surface I think I wouldpurchase a Knight Disc Elite or Extrem before I would purchase a Rem Genesis, but without seeing what you have in mind that is a difficult call.
So in effect I have not helped a bit...
