In reply to FockeWulf:
The Allalinhorn and the Breithorn regularly get suggested as the easiest 4000ers because you can get very close from the lifts. That is true, I think. Not sure exactly what you tried last year but if the lifts aren't running I wouldn't have said they were particularly easy, and if the lifts are running they're not really good practice for the long days required for Mont Blanc, if that's what you're working towards.
On the Allalinhorn in particular, I would say that the glacier is getting much worse recently, and it might be a bit exciting if you're not used to that sort of thing. But equally on a good day there will be a steady stream of people so it won't be too adventurous.
If you want something with a 4000m summit, Lagginhorn or Weissmies (from the south) would be good over a few days, with some easy scrambling but not much in the way of glacier crossing.
